Stammer time: A brief look at psellismophilia

Over the Christmas holiday I received a notification from Google to say that my work on sexual paraphilias had been cited in an article entitled ‘Forget feet, meet the fetishists turned on by insects, stuttering and stairs’ on the Shoofee website. The article was a brief overview of seven paraphilias and fetishes, and many of those listed referred readers to articles on my personal blog. Of the seven listed, I had already written articles on six of them but I had never done one on the seventh – psellismophilia.

According to Dr. Anil Aggrawal in his 2009 book Forensic and Medico-legal Aspects of Sexual Crimes and Unusual Sexual Practices, psellismophilia is a paraphilia that involves becoming sexually aroused by stuttering. Psellismophilia is another paraphilia whose name has been derived as being the opposite of a specific phobia (i.e., psellismophobia, an irrational and persistent fear of stuttering). According to the Massive Phobia website, the root word ‘psellismo’ is the Greek word for ‘stammering’. The Phobia Source website notes stuttering as:

“A speech disorder wherein sounds, syllables or words are repeated or prolonged and this disrupts the normal flow of speech. This affects a person’s quality of life because people find it difficult to communicate with others and people might have also a hard time understanding people who stutter or might find it even annoying. Stuttering can be a source of ridicule and humiliation and this can lead to a full blown phobia called psellismophobia…We must remember that stuttering is not equivalent to lack of intelligence. In fact, most people who stutter are extremely intelligent and is said to be that their brains process their thoughts too fast and their speech can’t cope up with their thoughts”.


As with any human behaviour that I know little about, I first did a search on Google Scholar and found that no article had ever been written on the topic. I then did a simple search on Google and again found that no articles had ever been done on the behaviour. However, there were plenty of articles that mentioned it in passing including articles in The Huffington Post (‘46 sexual fetishes you’ve never heard of’), Crave Online (‘15 bizarre sexual fetishes you’ve probably never heard of’), The Buzz (‘15 bizarre/disgusting sexual fetishes you’ve probably never heard of!’), The Thrillist (‘20 bizarre sexual fetishes you never knew existed’), The Sex Health Mag (‘The 10 strange sexual fetishes you’ve probably never heard of’), The Hook Mag (‘20 of the most f**ked up sexual fetishes you’d prefer not to know about’), and The Inked Mag (‘50 shades of weird. 49 of the most bizarre sex fetishes!’). Not one of these articles had anything more than a one-line definition (typically describing the condition as an abnormal affection and/or love for stuttering). The article in Shoofee, did offer a little more in the way of explanation:

“Stuttering affects one percent of the world’s population and many sufferers find themselves the butt of jokes. But if they were to come across a psellismophiliac they could find that their speech is an instant aphrodisiac, for this is a fetish which involves arousal to stuttering. Natalie, a 22-year-old psellismophiliac, explained her condition on an online psychology forum. ‘I feel like I can’t date regularly because I won’t be sexually interested in anyone who doesn’t have a stammer,’ she wrote. Natalie added that when she mentioned it to boyfriends they tried to pretend to stutter but she said it failed to arouse her like the real thing”.

Given the complete lack of information on whether there are individuals who are sexually aroused by stuttering I began trawling various online forums and began to find individuals who confessed online that stuttering was something they found sexually arousing (or claim to know those who are). Obviously I have no way of knowing the veracity of the claims made, but most appeared to be genuine to me. Here are some extracts:

  • Extract 1: “I am a girl who finds listening to a guy stutter and struggle extremely sexy… no there is very little on the internet about it, guess there’s not many of us out there, but you’re not alone” (Lickerish, female, heterosexual).
  • Extract 2: “I’m a guy who gets turned on by listening to a girl stutter, and I’ve never been able to figure out why…There’s hardly anything on the internet about it, other than this thread and a few random ‘stuttering is sexy’ one-liners on other sites…But yeah, there are a few of us out there, and it’s interesting to know that it’s not limited to just one gender” (Wireless Mike, male, heterosexual).
  • Extract 3: “I’ve had this fetish for years (I’m 31 now), but it’s been getting stronger and stronger. I’m a gay guy attracted to other guys who stutter. I’ve met a couple of guys locally and a couple more over Skype. We are still friends with [three] of them – we just drifted apart with the other one since time zones don’t work to our advantage. But I find myself wishing I had more friends who stutter to talk to. It’s both a sexual thing and a non-sexual thing… in some ways I prefer chatting with guys who stutter than fluent guys…Does anyone else feel the same? It’s frustrating that I have to work so hard to convince others I’m not crazy” (Jay, male, gay).
  • Extract 4: “I had a chick ask me to stutter on her nether regions once. It’s about the closest I’ve seen of a “stuttering fetish” (Zachary, male, heterosexual).
  • Extract 5: “I have [a stutter fetish]. I’m female and I like men, but I have this fetish for males and females. I’ve never written this before. Certainly never said it” (Spector, female, bisexual).
  • Extract 6: “I don’t have personal experience with people fetishizing stuttering, but I’ve seen it, particularly in smutty fanfiction with ‘nervous’ submissive characters” (Croagunk, male, sexuality unknown).
  • Extract 7: “I once dated a girl who confessed during our brief relationship that she thought my stutter was ‘cute’. I’m pretty sure she was into ‘different’ kinds of guys. She would always bring it up and stare at my mouth. It was like a fetish. It was like she had a thing for disabled guys! I broke up with her not because I didn’t like her, just because it freaked me out. Made me feel really uncomfortable” (priateproducer, male, heterosexual).
  • Extract 8: The stutter can be sexy. The thing of gasping for air; moving tongues; flailing lips; breathing. These are sexual motions, these are movements of the mouth, the delicate lips, the waving of the soft tongue. To stutter is to wave the soft flesh of the face in rapid succession…Thinking about stuttering as an intimate act, akin to being naked, may change its constructed meaning and turn it into a moment of closeness with our community” (Zach, male, sexuality unknown)
  • Extract 9: “I am a guy who likes guys, and consider myself to have a stuttering fetish…It’s true that there isn’t much [online about] this, but I’ve spoken to 4 or 5 other guys (through the net and on the phone/skype occasionally) who also share this – so I’m not the only one!…I can’t quite explain it, but I really like guys who stutter. Let me say that it has to be more than just that to like a guy, but it helps!…For me, the more severe the stutter the more attractive it is. I’ve spoken to a quite a few guys who stutter and I’ve always been open about this. Some just find it strange or think I’m kidding, but most are really open and relieved to find someone who doesn’t have an issue with it. For me it’s not as simple as just a ‘fetish’, I’ve read a lot about it and can understand a lot about it. I’ve also talked to a couple of guys who like to pretend (even though they’re completely fluent otherwise) and I find that interesting too” (Jay, male, gay).
  • Extract 10: “I have a stuttering fetish…I look for videos of stuttering online to watch. The more severe the stutter, the more struggle and secondary characteristics, the better. I stuttered pretty badly as a child, and occasionally still do…It’s nice to know I’m not the only one” (eglorae, gender and sexuality unknown).
  • Extract 11: “I’m new on this forum so I was just only browsing and saw the stuttering topic and it immediately caught my attention so…yes I guess I have a soft spot for guys who stutter. It’s not quite a fetish, but I find it really cute and sexy. I used to [have] a crush on a guy when I was like 14 years old and he was a stutterer, oh his speaking was so hot!” (Alexandra, female, heterosexual).
  • Extract 12: “Wow, I thought I was the only one and that I was odd! I’m a guy who finds stuttering really sexy in women. No idea why…It’s just something I discovered that I like. I’d love to talk…with some girls who stutter but it seems very unlikely!” (emmanola, male, heterosexual).
  • Extract 13: “I have to tell you, that some of the guys I have met have found it an absolute turn on for them. During intimate moments my stuttering gets a lot worse which can send some guys crazy, although admittedly it is a very small number. I never thought it as being a fetish though, but maybe it is. I can’t say that anyone I have met has been actually looking for someone that stutters but rather looked at is a bonus when they found someone that did” (Kenny, male, gay).
  • Extract 14: “I stutter and it is a BIG turn-on for me. It’s nice to know that I’m not the only one. I would love to talk to another stutterer – especially one who thinks it’s a turn-on” (Stutteringdude, male, gay).

Based on these online self-confessions, a few things can be concluded. Obviously I have no idea about whether these are in any way representative of those individuals who like those that stutter, but if it is a genuine fetish or paraphilia (and some of these individuals claim it is something they like strongly or have a preference for rather than it being a fetish as such), the behaviour appears to prevalent in both men and women and not be associated with one particular sexual orientation as it was described by those both gay and straight. Very few appear to know where their fetish for stuttering originates although some describe memories from adolescence and being sexually aroused in the formative stages of sexual development. Most see the fetish as something that they have kept to themselves without ever having talked to others about it. Some appear to be glad that they ‘are not alone’ in having the fetish and find comfort in hearing others’ stories. Some individuals went as far to offer explanations for the fetish or what it’s not about.

  • Extract 15: ‪I think I know what attracts [people] to the stutter. I think it’s most likely the tonality of a stutter. They raise in pitch, repeat syllables that sometimes mirror those of an orgasm or basic sexual moaning. I honestly do think you might find something a bit erotic about how similarly a stutter can mimic that of sexual moan…even the facial expressions made” (aimoo182, gender and sexuality unknown).
  • Extract 16: “I’ve also read a bit about stuttering and can understand a lot more than your average guy. I’ve been asked if it’s a [domination] thing…it’s not. I’d happily dom or be dommed by a guy who stutters. Or just hold a nice conversation. It doesn’t matter” (Jay, male, gay).

My own view is that most fetishes and paraphilias appear to begin developing in early adolescence and that classical conditioning (i.e., associative pairing between sexual arousal and the non-sexual stimulus, in this case the stuttering) is an important part of the acquisition process. Little of what I found fits my opinion on this but that’s more because the individuals themselves have little insight to their own behaviour and how the fetish manifested itself. Whether psellismophilia ever becomes the focus of serious academic study remains to be seen but I doubt that it will unless any negative consequences arise from the behaviour (and I have come across nothing suggesting that the condition – if it genuinely exists – is any way detrimental).

Sexed text and lust discussed: Another brief look at cybersex

The advent of the Internet has enabled people’s engagement in a wide variety of online sexual behaviors. The Internet can provide a “safe” space for sexual exploration that presents less physical and social danger than offline activities, and may also provide access to a social community and a support system for non-normative gender and sexual expression (e.g., sexual fetishes and paraphilias). Additionally, a small minority of people may use the Internet excessively to engage in cybersex. Rather than being complementary, their use of cybersex may become a substitute for their offline sexual lives. For a small minority, their behaviors may take on addictive qualities that can be indicative of an online sexual addiction.

I noted in a number of papers that I published in the early 2000s (e.g., Journal of Sex Research [2001] and CyberPsychology and Behavior [2000]; see ‘Further reading’ below) that the Internet can be – and has been – used for a number of diverse activities surrounding sexually motivated online behavior. These include the use of the Internet for (i) seeking out sexually related material for educational use, (ii) buying or selling sexually related goods for further use offline, (iii) visiting and/or purchasing goods in online virtual sex shops, (iv) seeking out material for entertainment/masturbatory purposes for use online, (v) seeking out sex therapists, and (vi) seeking out sexual partners for an enduring relationship.


Other sexually motivated uses of the Internet include (i) seeking out sexual partners for a transitory relationship (i.e., escorts, prostitutes, swingers) via online personal advertisements/“lonely hearts” columns, escort agencies, and/or chat rooms, (ii) seeking out individuals who then become victims of sexually related Internet crime (online sexual harassment, cyberstalking, pedophilic “grooming” of children), (iii) engaging in and maintaining online relationships via email and/or chat rooms, (iv) exploring gender and identity roles by swapping gender or creating other personas and forming online relationships, and (v) digitally manipulating images on the Internet for entertainment and/or masturbatory purposes (e.g., celebrity fake photographs where heads of famous people are superimposed onto someone else’s naked body)

More recently, in a 2012 issue of the journal Addiction Research and Theory, I noted that online sexual behaviors can be classified as either cybersexual consumption (i.e., downloading and watching sexual content online such as pornography or reading sexual content in forums/chat sites without actively participating), or cybersexual interaction with others (e.g., text-based chat and/or video-linked conversations). Either of these types of online behavior may be accompanied by concurrent masturbation. Furthermore, online activities with a sexual component can be problematic for some because (1) they manifest sexual desires that the person (or their offline sexual partner) disapprove of or feel guilty about; (2) they divert (or distort) sexual energy from offline sexual behavior; and (3) the search for the ideal online sexual material may take up a great deal of time. Therefore, it appears necessary to distinguish not only between consumptive and interactive cybersex, but also between “normal” and “deviant” online sexual behaviors.

The late 1990s and early 2000s experienced a proliferation of studies investigating how human sexual behavior is enacted on the Internet. Some scholars (such as James Quinn and Craig Forsyth in a 2005 issue of the journal Deviant Behavior) claimed that technology transformed vicarious sex into an increasingly viable and attractive substitute for interpersonal forms of sexual fulfilment. Such an assertion suggests that a minority of cybersex users may use the Internet as a substitute for offline behaviours. It also suggests that what happens online may be very fulfilling for some people.

Sex on the Internet is particularly viable because of the inherent qualities of the Internet that the late Dr. Al Cooper referred to as the ‘Triple A Engine’ (access, affordability and anonymity). The online world, including explicit sexual material as well as potential online and offline sexual partners, can be accessed anytime and anywhere. Most of the time, sexual activities can be pursued at virtually no cost online, a point that demarcates online sex from offline sex, considering the expenditures involved in buying sex tapes or paying for sex workers. In comparison, the costs for bandwidth access are relatively low.

As an adaptation to Dr. Cooper’s Triple A Engine, Dr. Kimberley Young and colleagues proposed the ACE model, incorporating anonymity, convenience, and escape as factors salient to the Internet. These factors facilitate the engagement in sex by decreasing the inhibition thresholds present in offline sexual relations. Not only is a person anonymous online, but the Internet is ubiquitous and it can be accessed conveniently from a safe base, such as the person’s home.

Compared to offline sex, the Internet appears to offer the possibility to engage in cybersex anytime and anywhere for little financial cost. Therefore, research studies have found individuals are more likely to engage in risky sexual behaviors on the Internet rather than offline. The lower threshold associated with perceived lower risks of engaging in online sex may therefore increase the chance of persons who are at risk for developing sex addiction offline to actually develop sex addiction on the Internet. Empirical studies have increased our understanding of specific online sexual activities (e.g., Internet sex addiction). Here, the distinction between people who use Internet sex to improve their offline sex life and those who use it as a substitution may play an important role. Furthermore, cross-cultural differences point to the fact that the sociocultural context plays an important role in influencing people’s attitudes toward sexual behaviors.

In line with this, two potential scenarios materialize. First, one might assume that as views of sex are relatively liberal in some cultures relative to other more conservative cultures, members of the former may be more likely to engage in sex on the Internet because they have more open attitudes toward sexuality in general. Alternatively, particularly because some cultures are relatively conservative when it comes to sex, their members could potentially be more likely to engage in cybersex in order to compensate for the lack of freedoms in expressing their sexuality offline.

The wows of brows: Eyebrow fetishes and the naming of a new paraphilia

Over the years I have written about many different body part fetishes and paraphilias including a number involving human hair (or the lack of it). These have included individuals that are sexually aroused by (i) human hair in general but usually head hair (trichophilia/hirsutophilia), (ii) female body hair fetishism, (iii) beard fetishism (pogonophilia), (iv) haircut fetishism, (v) armpit hair fetishism (maschalagnia), (vi) depilation and shaving fetishism, and (vii) baldness fetishism (acomophilia). [I’ve also written articles about uncombable hair syndrome and hair dryer dependence].

The reason I mention all this was that a few months ago I got an email from a man asking if I had ever come across individuals with a fetish for eyebrow hair. He claimed he had a fetish for women with “big bushy eyebrows” and gave the example of Cara Delevinge (the model and actress who played the Enchantress June Moone in the film Suicide Squad). I wrote back to him and told him that I had never come across anyone but would have a look into it (and this blog is the consequence).


As far as I am aware, not only is there no academic or clinical research on the topic of eyebrow fetishes, but there aren’t even any articles (this I believe is the first ever article on the topic). There was nothing between in Dr. Brenda Love’s Encyclopedia of Unusual Sex Practices and nothing in Dr. Anil Aggrawal’s Forensic and Medico-legal Aspects of Sexual Crimes and Unusual Sexual Practices. Eyebrows weren’t even mentioned in the list of fetishized body parts in Dr. C. Scorolli and colleagues’ excellent paper on the prevalence of fetishes in their 2007 paper in the International Journal of Impotence Research (a study I have cited countless times in relation to my blogs on other sexualized body parts).

As a final resort I went searching on the internet but was unable to locate a single online forum that was dedicated to those who have eyebrow fetishes. However, I did locate a few individuals that claimed they had eyebrow fetishes (or at least some behaviour indicative of some kind of eyebrow fetish). Here are a few examples:

  • Exract 1: “I’m not that attracted to a lot of girls. I mean yeah there’s hot girls but [I’m just not] into them. ([I’m] not gay). But I’ve notice the girls I am interested are while girls with thick wavy eyebrows and I admire those, and yeah the girls are pretty too. But I find it weird that I like eyebrows really much!
  • Extract 2: “I’m not sure, but I think people think I’m weird. I like to stare at other people’s eyebrows, sometimes I reach out to touch them but they run away…One time, I masturbated in class over Casey’s bushy brow and I squirted everywhere. The teacher and everyone were staring with a sort of disgusted look on their faces. I don’t know why though? Is this not normal?”
  • Extract 3: “Okay, is it weird that I find guys with really nice eyebrows sexy or when a guy has a nice beard, not puffy…like Adam Levin’s beard. AND WHEN A GUY HAS BOTH….YOU DON’T EVEN KNOW WHAT IT DOES TO ME…When a guy has nice eyebrows, I just want to fangirl over them and stare at them. Too bad, the guys my age don’t have nice eyebrows”
  • Extract 4: “I know I have [a nose and eyebrow fetish], and if someone doesn’t have a nose shape I like I just can’t be attracted to them – same with the eyebrows. It’s the weirdest thing, I could literally pet a man’s eyebrows for prolonged periods of time”.
  • Extract 5: “I have an eyebrow fetish for as long as I can remember…I’ve been through A LOT of different eyebrow stages, caterpillar eyebrows, Yankee eyebrows. Then came the flat eyebrows without much of an arch. And now I finally have eyebrows that people might say are normal”
  • Extract 6: “I have had a fetish with eyebrows. I can’t help but study a woman’s brows when we are talking or am looking at someone at a distance. I have been shaping my brows for over 20 years and over past 10 years my brows have gone from shaped to thin and even shaved off couple times smooth. Yes I said smooth. I currently have very thin eyebrows. Like 2-3 hairs wide from start to end. Usually they are a little thicker like maybe 5 hairs wide. My wife is a hairdresser and she waxes them every 2 weeks or so. I have worn them for a while clippered next to skin and thin. I wax my wife’s brows every 3 weeks but she likes a more natural look and arched. I did however get her to let me clipper cut them shorter so they were not so thick ‘n’ long. looks great now that they are shorter. My ex-wife allowed me to keep her brows fairly thin and that was great”.
  • Extract 7: “I love shaved naked eyebrows on ladies or very thin/pencil thin arched eyebrows on ladies. I think it is very sexy and unique. I myself very thin eyebrows. Like 3 hairs wide from start to finish. [I] have shaved them smooth several times while on vacation from work…I am attracted to ladies with very thin eyebrows. Just something I notice and love”.

Obviously I can’t vouch for the veracity of these quotes but they appeared to be genuine. However, based on the self-confessions I found, there is little in the way of definitive conclusions. All of the individuals appeared to be heterosexual and males were more likely than females to claim they had such a fetish (five of the seven extracts were by males). None of the information I found gave any clue as to the etiology of their love for eyebrows although no-one found their fetish in any way problematic. Two of the individuals said their fetish for eyebrows was not their only focus of sexual attraction (with noses and beards also being cited as an additional source of sexal arousal). Given the apparent rarity, I doubt that this type of fetish or paraphilia will ever be the topic of academic or clinical study.

Given the complete lack of scientific study relating to eyebrow fetishes I have decided to name a new paraphilia – if it exists – based on traditional nosology using the Greek words for ‘eyebrow’ (frýdi) and ‘love’ (philia) – thus this ‘new’ paraphilia is called frýdiphilia.

The night stuff: A very brief look at nyctophilia and scotophilia

According to Dr. Anil Aggrawal in his 2009 book Forensic and Medico-legal Aspects of Sexual Crimes and Unusual Sexual Practices nyctophilia is a sexual paraphilia where the individual derives sexual pleasure and arousal by a “love of night”. In the same book, Aggrawal defines similar (if not the same conditions) including scotophilia (“turned on by darkness”), lygophilia (“love of darkness”) and achluophilia (“arousal from darkness”). Another related condition is arguably amaurophilia (“arousal by a partner who is blind or unable to see due to artificial means such as being blindfolded or having sex in total darkness”, a paraphilia that I examined in depth in a previous blog). Other sources (such as Dr. Brenda Love’s Encyclopedia of Unusual Sex Practices doesn’t mention any of these, apart from amaurophilia) whereas other medical dictionaries conflate darkness and night together and define nyctophilia as a “preference for the night or darkness. Also called scotophilia”.

As far as I can ascertain, there is no empirical research on this topic at all. There are many references to the similar sounding scopophilia (viewed by many as another term for ‘voyeurism’) but as Dr. Aggrawal notes:

“Several terms have been used as synonyms of voyeurism, although some writers have constantly pointed out subtle differences. The terms scopophilia and scoptophilia are taken as synonyms to voyeurism by most writers. However, others have pointed out a minor difference. If the victim is unsuspecting and non-consenting, the act is voyeurism, but if the other party is consenting, the act is scopophilia or scoptophilia. Furthermore, if the person watched is in the act of disrobing, or nude, the act is voyeurism, but if the person watched is engaged in sex, the act is either mixoscopia (if the watched person is the voyeur’s lover) or allopellia (if the watched persons are complete strangers)”.


The reason I mention this is because in a paper by Dr. Patrick Mahony on voyeurism in a 1989 issue Journal of the American Psychoanalytic Association noted that the “alternate spelling scoptophilia, preferred by some of the older German psychoanalysts, must not be confused with scotophilia or love of darkness”. This appears to have happened in other academic papers I found directly referring to ‘scotophilia’. For instance, one paper dating back almost 70 years was that of Dr. F.S. Caprio who wrote a paper entitled ‘Scotophilia–exhibitionism: A case report’ in the Journal of Clinical and Experimental Psychopathology but it was actually a paper about voyeurism. More specifically, the paper reported the cases of a mother and son who constantly watched residents for sexual arousal in the mother’s rooming house via drilled holes in the wall. A 1966 theoretical review paper by Dr. Jerome Sattler on embarrassment and blushing published in the Journal of Social Psychology claimed that “stage-fright and erythrophobia [fear of blushing] are not simply expressions of the warding off of heightened exhibitionism and scotophilia but also develop as a result of previous instinctual conflict”. Here again, scotophilia appears to be a synonym for voyeurism rather than a sexual love of darkness.

I was pleasantly surprised to find dozens of references to nyctophilia in the scientific literature but the overwhelming majority of papers were biological in origin and all referred to non-human species. For instance, a recent 2016 paper Dr. Luis Espinasa and colleagues in the journal Subterranean Biology reported that cave amphipods are eyeless troglobitic crustaceans found in caves located in the Northeastern (Allegheny) region of the United States and who “exhibit nyctophilia” (literally meaning they love darkness, and has absolutely nothing sexual whatsoever).

I only managed to find one non-biological academic reference on nyctophilia and this was a 1994 paper by Dr. Lewis Lawson in the journal Papers on Language and Literature. In actuality, the use of the word ‘nyctophilia’ was mentioned in passing and noted that the term was defined by psychoanalyst Bertram Lewin as “an erotic pleasure in darkness, which enters as a wish-fulfillment element on fantasies of being in the ‘womb,’ or more properly, as the German word Mutterlieb suggests, of being in the mother’s body”. I was unable to track down the original source so I don’t know the context in which Lewin used the word but the definition is certainly used in a sexual sense rather than the general ‘love of darkness’ used in the biologically-based papers.

In a more general search on the internet, located dedicated photographic sites for nyctophilia, a number of fictional books with the title of Nyctophilia (such as the novel by Welsh author K.A. Hambly), and even the name of a 2014 film (although details about it are sketchy to say the least). I also came across one first-person account of nyctophilia online from someone who has written a number of different articles about the condition such as ‘What is nyctophilia?’, ‘What is it like to have nytophilia?’ and ‘Everything you wanted to know about nyctophilia symptoms’. However, detailed reading of these articles suggests that any sexual element is secondary to a general love of darkness. Here are a few extracts from the articles:

Extract 1: “I have a confession to make. I am a nyctophiliac…Well, a lot of people have told me that I am an insomniac. An insomniac is someone who has difficulty sleeping at night. But I have realized over time that I am not just an insomniac. Insomnia is a physical condition, not a psychological one. Nyctophilia, on the other hand, is purely a psychological condition. Many say that nyctophiliacs are sexually aroused by the dark. Is that true? Well, yes and no. I like darkness, but I am not always sexually aroused by it. I just love it for what it is. It gives me a sense of relief and it makes me happy”.

Extract 2: “To help you understand nyctophilia symptoms, [here] I reveal some uncomfortable details of my life. Every night, I try to sleep at 10 pm. I take sleeping pills such as Klonopin and get myself a good book to read. When I do fall asleep, at around 10:30 pm or 10:45 pm, I find myself waking up at 12:00 am sharp, as fresh as the day, as though I’ve been asleep for 9 hours. I am wide awake at this time and no matter what I do, I cannot go to sleep. Unlike an insomniac, who would turn the lights on and perhaps watch TV, that’s the last thing on my mind. I just want to sit in the bedroom chair in the dark, all alone, with just darkness as my company. I love the darkness. It makes me happy. I feel a sense of relief as I sit in the dark and listen to the sound of the clock ticking by. I know it’s not good for me to stay awake like this, like a ghost, in complete darkness. I tell that to myself several times and often I try my very best to sleep. That is when I get those dreams. Those horrible dreams. The nightmares. I find myself in impossible situations, either getting tortured like Mel Gibson in Braveheart or dying of a dreadful disease, like a child affected by the Ebola virus in Africa”.

Extract 3: There isn’t much of an awareness of nyctophilia, or nyctophilia symptoms, out there on the Web…The defines nyctophilia as ‘The love of darkness or night, or feeling like you belong in the dark” and adds that the condition ‘usually applies to those who often feel sadness!’ Nyctophilia is a condition that makes you want to sit in the dark all by yourself late at night, wide awake…You may wander off late at night in the dark. This will get you in trouble with the authorities, who do not really understand the nyctophilia meaning and cannot even comprehend how you feel. So you may get mistaken for a sex addict or a pervert, or possibly a criminal. Your neighbors would avoid you and report you to the law enforcement agencies. They would want you to leave the neighborhood and move somewhere else. They would feel distinctly uncomfortable about your condition and word would get around about the fact that you stay up all night in the dark, basically doing nothing”.

Extract 4: “There are many who say that nyctophialiacs find darkness sexually arousing. They compare the condition to a form of sex addiction. Indeed, have been given medication for sex addiction, such as GnRH, a long lasting gonadotropin releasing hormone that suppresses sexual desires. If you feel that you have any of the nyctophilia symptoms…it is important to get yourself treated by a qualified psychiatrist, preferably someone who has experience of working with modern or unusual psychiatric conditions. Take the medications that are suggested to you and ask support from your friends and family”

In all the reading I have done on this topic, there appears to be very little genuine evidence that scotophilia and nyctophilia exist, and if the condition does exist, few people appear to suffer major problems as a consequence, unless their love of the dark leaves the person feeling so sleep-deprived that it interferes with their day-to-day functioning. Maybe this condition is a sub-type of insomnia but that the underlying reasons for not going to sleep are very different from the usual reasons for not being able to sleep.

Car-struck: Another look at mechanophilia and objectum sexuality

“There is no one in the world Darius Monty loves more than Goldie. With her perfect curves and flawless body, she’s a beauty. And the pub boss’s sex life with the hot model less than half his age is better than with any previous girlfriends. But shockingly the object of his full-on passion is a CAR. While many men claim to love their motors, Darius is IN love with his gold-coloured X-Type Jaguar – and makes love to ‘her’” (Sunday Mirror, July 30, 2017).

The opening quote comes from a story that appeared in last weekend’s Sunday Mirror and for which I also supplied some accompanying text in the published article. I described Darius as more of an objectophile than a mechanophile (although he does fit both definitions). According to Dr. Anil Aggrawal’s 2009 book Forensic and Medico-legal Aspects of Sexual Crimes and Unusual Sexual Practices, mechanophilia refers to those being sexually turned on by machines although Cynthia Ceilán in her 2008 book Weirdly Beloved: Tales of Strange Bedfellows, Odd Couplings, and Love Gone Bad describes the same sexual paraphilia as ‘mechaphilia’.


Objectum sexuality refers to those individuals who develop deep emotional and/or romantic attachments to (and have relationships with) specific inanimate objects or structures. Such objectophiles express a loving and/or sexual preference and commitment to particular items or structures (and this is why I view Darius as more of an objectophile than a mechanophile). It has also been claimed (by academics such as Amy Marsh – see ‘Further reading’ below) that such individuals rarely (if ever) have sex with humans and they develop strong emotional fixations to the object or structure. Unlike sexual fetishism, the object or structure is viewed as an equal partner in the relationship and is not used to enhance or facilitate sexual behaviour. Some objectophiles even believe that their feelings are reciprocated by the object of their desire. According to the Sunday Mirror article:

“Darius fell in love with his Jaguar after buying the executive saloon two years ago [in 2015]. His second-hand limo, which was built…in 2004, has startled Darius with the feelings it has aroused. Yet Darius could not fight the urge to live out his sexual fantasies with the car. His passion for Goldie soon became a daily ritual after he returned from his night shift at the pub. And eventually he realised he could no longer hide it from his loved ones. Darius resisted professional help because he thought his liaisons with his motor would become less exciting with time. Despite the negative reaction from his mates, Darius refused to give up on Goldie. Bizarrely, Darius says his relationship with Goldie has gone from strength to strength. He has even retired her from life on the road to keep her in pristine condition. Astonishingly, Darius would still like to find a human girlfriend”.

Unlike most objectophiles I have read about, Darius had sexual relationships with women prior to falling in love with Goldie, and still wants sex with women in the future. In his interview with the Sunday Mirror, he was reported as saying:

 “I don’t expect people to understand because it’s not something I fully understand myself. I didn’t choose this but I have fallen for a car, just like other people fall for women. I find her arousing, I love spending time with her and she is very important to me. I don’t see her as an object, I look at her and I see my lover. Before I bought Goldie I was in a normal loving relationship with a woman. I didn’t see anything strange about myself or my sexuality at all. I’ve always been a car lover, but if someone told me it was possible to have sexual feelings towards something that’s not human I’d have laughed them off just like people laugh at me now. I can’t really explain what triggered it, but I went to view Goldie and had always wanted an X-Type Jaguar. Her colour is so unique and after I’d handed over the cash, all I wanted to do was go and polish her. I pulled into the jet wash and was making circular motions on her bonnet with a cleaning cloth when I suddenly felt unexpectedly aroused. It was something about the smooth, shiny paintwork and the perfect curves of the car that got me turned on. I tried to ignore the feeling and just put it down to excitement about having a new car. But when I got home and sat down to watch TV I had a real urge to venture into the garage and visit her in private”.

The unexpected sexual arousal that Darius felt when first polishing Goldie appears to be the initial spark of his relationship with the car. Psychologists like myself would claim that this unexpected associative pairing of polishing the car with sexual arousal is something that repeatedly played on Darius’ mind and that this formed the basis for a classically conditioned response where the car itself ended up causing the sexual arousal. As he also explained in his newspaper interview:

“I had a girlfriend at the time and I didn’t dare tell her what was going through my mind so I used the excuse that I’d left my wallet in the car and headed out. I wasn’t exactly sure what would happen as the feelings were all new to me. I just knew I felt really turned on by the notion of having sexual intercourse with my new car. Immediately afterwards I felt ashamed and guilty, but I knew right then it wouldn’t be the last time. I walked away feeling so confused about what I’d just done. As disturbing as it was, I told myself I couldn’t be the only person in the world who had experienced these kinds of feelings”.

And Darius was right. There are dozens of objectophiles around the world, and while the behaviour is rare, he is certainly not alone. For instance, in a previous blog I recounted the stories of Edward Smith (an American man who has who has had sex with over a 1000 cars), and Robert Stewart (a British man who ended up in court after being caught having sex with a bicycle). It was when Darius started doing his own research on his behaviour that he began to feel better, knowing there were other objectophiles:

“Knowing others had [sexual and romantic] feelings towards cars, bikes or planes definitely put me at ease but it was a really difficult thing for me to accept. I was enjoying having sex with my car more than with my girlfriend. I even missed the car when I went up to bed at night and felt bad for leaving her alone in the garage. When I broke the news to my girlfriend she left me right away. I could understand her thinking my behaviour was odd, but deep down there was a sense of relief there for me in knowing that I had got things out in the open and I was free to pursue my relationship with Goldie”.

Having accepted that the feelings towards his car were not unique, Darius began to share the details of his new love with his closest friends:

“They laughed at first thinking I was joking, but once they realised I was being serious they told me I was weird and that I need to get psychological help. It really upset me knowing I didn’t have any kind of support or understanding from other people. My feelings for [the car] just grew stronger and stronger. I have never had loving or sexual feelings for any other vehicle, and I firmly believe I have something special with Goldie. I realise most people will think what I do is wrong in some way, but I’m not hurting anyone so what’s the harm?”

In my commentary on the case for the newspaper, I claimed that there was nothing wrong with Darius in a psychological sense. Yes, his behaviour is strange, yes his behaviour seems bizarre to most people, and yes it’s unusual, but he Darius doesn’t appear to need psychological treatment. I noted that if Darius wanted to spend the rest of his life living in a non-normative relationship with Goldie that does no harm to him or anybody else, that was OK by me. I have no problems with anybody’s sexual behaviour as long as it’s consensual (and in this case, the car can’t say it’s not OK). If others see his behaviour as bizarre, it is totally irrelevant. Darius can seek treatment if it’s psychologically harming him, but it sounds like he knows it’s unusual and he seems fine with it. As he went on to say:

“[Goldie] doesn’t cheat on me or moan about me not doing the washing up. She doesn’t have the ability to be in a bad mood. I haven’t lost sight of the fact Goldie is a machine and probably doesn’t love me back – I am not delusional in the sense I’d think she has her own mind. I’ve met a few women since falling in love with Goldie and I am always completely open about her from the start. A couple of them have been open to giving things a go, but when I take my trips out to the garage to see her they say they just find it all too weird. I’d love to get married and have a family if I’m honest. But the next woman I date will have to be OK about sharing me with Goldie”.

In a previous blog, I provided details of the only academic paper that has been published concerning a car-loving objectophile but that case was very different to that of Darius. The paper was a case study by Dr Padmal De Silva and Dr Amanda Pernet published in a 1992 issue of the journal Sex and Marital Therapy. The case involved an unusual sexual deviation in a young 20-year old British man (‘George’) who had little social interaction and was incredibly shy. They reported that his main sexual interest and excitement was from cars – particularly Austin Metro cars. George’s family belonged to a strict religious sect who strongly disapproved of any sexual involvement by their son with women. Things changed for George when his parents bought an Austin Metro car. George began masturbating inside the car, and then outside masturbating outside the car while crouching down next to the car’s exhaust pipe. So that he couldn’t be caught masturbating, he would go to great lengths to find deserted places to engage in his sexual activity with the car.

George used to become very sexually excited when the car’s exhaust pipe was running and pumping out car fumes. This aspect of “elimination” – according to De Silva and Pernet – was an important central element in George’s other sexual preferences – particularly his fascination of urination. As a very young child he had an unusual interest in dogs urinating. After the age of 10 years, he was more interested in children and adult women urinating. The authors also speculated there may have been an increase in George’s arousal due to a “reduction of oxygen intake and related asphyxiation”. This was possibly seen as a mild form of hypoxyphilia.

As you can see, the case of ‘George’ and Darius share few similarities apart from the fact they both have sexual relationships with cars. The fact that two case studies can be so different is terms of aetiology and development of the behaviour suggests that car-loving objectophiles should be an avenue of further research because there are likely to be very different explanations and motivations for the behaviour.

Thigh high: A brief look at thigh fetishism

Thigh fetishism might appear a somewhat obvious topic to write a blog on given all the previous body part fetishes I have looked at (including foot fetishism, shoulder fetishism). However, there is no academic research on the topic and most non-academic articles that I have read tend to concentrate on thigh-boot fetishism rather than thigh fetishism in, and of, itself. According to the Kinkly website:

“Thigh fetish refers to a sexual arousal by or sexual interest in thighs. Typically, it is a male interest in female thighs. However, it can apply to a woman’s interest in female thighs, a woman’s interest in male thighs, or a male’s interest in male thighs. Usually the fetishist is attracted to the naked thighs. The thighs don’t even need to be extremely sexualized for the fetishist. Often it is the gap between a high boot and edge of skirt, or knee high socks and edge of skirt that arouse the fetishist more than sexualized images of thighs”.


The Self-Help Sexuality website adds that “some men have a thigh fetish where they are turned on by the glimpse of woman’s inner thigh or when a woman opens her thigh. Some men enjoy kissing and licking woman’s inner thigh”. Both of these descriptions are fairly commonsense and arguably don’t need empirical research to back up the claims made.

Thee one piece of empirical research I found with some reference to thigh sexuality was a paper published in a 2014 issue of the journal Cortex by Dr. Oliver Turnbull and colleagues who examined which erogenous zones are the most sensitive in males and females. They surveyed 800 participants (mainly British and Sub-Saharan Africans) and were asked to rate 41 body parts for erogenous intensity on a 10-point scale. Unsurprisingly, the highest rated body parts for sensitivity were the clitoris among women (mean rating 9.17 out of 10) and the penis among men (mean rating 9.0 out of 10). Inner thighs were rated as the fourth most erogenous zone by men (mean rating 5.84 out of 10; back of thigh 2.48 out 10; outer thigh 1.91 out of 10), and the seventh most erogenous zone by women (mean rating 6.7 out of 10; back of thigh 2.6 out 10; outer thigh 1.96 out of 10).

I also found details of a non-academic online survey among Japanese businessmen (mainly those in their thirties and forties) carried out by the marketing research company Goo via an article on the Japanator website. The focus of the survey was favourite “secret fetishes”. Top of the 20 listed fetishes was zettai ryouiki (which translates as “absolute territory”) and refers to the “leg exposure located between the hem of a skirt and the top of thigh-high socks”. The second-placed ‘secret fetish’ was also thigh-related and was being held in the vice-like grip of “athletic thighs”.

Regular readers of my blog will know that I’m fascinated by the sexual culture in Japan and have written many blogs on various aspects of Japanese sexuality. An article about thigh fetishes on the Venus O’Hara website specifically examined zettai ryouiki:

In other words, they fantasize most frequently about that piece of exposed flesh between the top of a girl’s thigh-high socks and the bottom of a short skirt. This description fulfils the fetish principle in that no nudity is involved. Zettai ryouiki describes an otherwise mundane detail which, when used as a primer for arousal, assumes a sexual significance that is almost impossible to explain for non thigh-fetishists. The same principle applies to Western men and the expression of their own thigh fetishism when it comes to lingerie and hosiery. Stockings and suspenders make these men’s enjoyment of thighs and their understanding of thigh fetishism that much easier. The combination of panties, a suspender belt and stockings isolates the area of exposed thigh and almost draws a border around it. This focuses the attention on the naked skin as oppose to the erogenous zones that are covered, albeit by material that is often sheer. A garter belt is another magnet for thigh fetishists, as are knee-high socks, thigh-high boots and self-support stockings”.

My own view is that thigh fetishism and other thigh-related fetishes (for thigh boots, thigh socks, etc.) while overlapping, are not the same. The article on the Venus O’Hara website then goes onto talk about another variant of thigh fetishism:

“Thigh fetishism has produced a new variation of itself recently and social media has had a lot to do with it. The trend for promoting and desiring a permanent clearance between the tops of the legs has become a social phenomenon and a modern yardstick for feminine health and beauty. This ‘thigh gap’ is more common, anatomically, in women who are naturally much taller and whose body mass index is lower than the average. The physiques displayed by contemporary fashion models are an obvious ideal where the ‘thigh gap’ is concerned. A much more democratic trend in relation to thigh fetishism has also arisen on social media almost in response to the ‘thigh gap’.  ‘Thighbrow’ describes the naturally-occurring crease between the thigh and the hip that appears when you sit or kneel down. Two of these, when observed together, have been said to resemble eyebrows. Whereas the ultimate ‘thigh gap’ seems to be exclusive to young women who wear size 6 jeans, the ‘thighbrow’ is a fetish highlight that everyone can flaunt”.

There was also a recent exhibition in Japan devoted purely to thigh fetishism. A short online article about the exhibition noted that:

“In Japanese Culture there are so many different fetishes that are popular: Swimsuit Fetish, Doorknob Licking Fetish (it’s not a joke), Teeth Fetish…Amongst these Fetishes, there is also Thigh Fetish, and Todays Gallery Studio decided to dedicate an entire photo exhibition about it…More than 500 works and 1000 pair of thighs shot by artist Yuria will be exposed”.

In my own research for this blog I was unable to find any dedicated online discussion forum for thigh fetishism. This could either be because it’s so rare or be because it’s so common that it’s not worth creating a dedicated website to discuss such matters. I found very few first-hand accounts of self-admitted thigh fetishism, in fact I only located two individuals:

  • Extract 1: “This is going to sound weird, but I sort of have a thing for women who have strong looking thighs. Size isn’t just what it’s about, but with a muscular tone along with it. It’s not like I get off on it, but I do find it very sexy and is a big turn on for me. It started when I seen a women at this gym who was wearing these spandex looking short pants and I couldn’t help but notice her thighs in them, and they were rather muscular. I don’t have a fetish for female bodybuilders, though I do find spandex sexy…but it wasn’t that, it was her thighs, and I just started noticing things like this more and more afterward”.
  • Extract 2Even before I hit puberty, I always had these strange, excited feeling in me…[When] I was 11, I would imagine these pretty girls getting out of their pants and revealing their legs…One night, I had an extremely arousing dream. It was odd, yet intense. I was hanging out in the park in my neighborhood. A bunch of ladies were hanging out…With no warning, all the ladies in the park started screaming. Their pants were undoing themselves. Afterward, all the ladies’ pants were being pulled off by something invisible and sex crazed. Something that wanted a bunch of ladies have no pants on. Now these scared ladies were in their underwear. The idea of these beautiful ladies going from having their pants on to being taken off them excited me to no end…My women’s thigh fetish was getting more intense…By the time I was 14, I imagined the sex crazed invisible creature taking off random women’s pants and making them cross their naked thighs together, like they were making out…When I was 14, I finally had found a girl…I told her all about my sexy dreams. About my women’s thigh fetish…I kept asking her really warped questions, like how she would feel if something took her pants off in school. How would she feel if her and another girl lost their pants together…[I] finally ejaculated and [was] happy that her legs were the reason…Even now…my women’s thigh fetish dreams were always my favorites to think about”.

I have no idea if these accounts are in any way representative of those who have a thigh fetish but both appear to be heterosexual males, and both can pinpoint where their interests in women’s thighs originated. As with many fetishes I have examined, I can’t see thigh fetishism being the topic of any in-depth empirical research simply because it has the ‘so what?’ factor. Who would be interested in such research and why?

Digital desires: A brief look at sexual thumb sucking and thumb fetishism

In previous blogs I have examined a number of extreme behaviours involving hands (both sexual and non-sexual) including hand wear fetishism, fingernail fetishism, ‘hands on hip’ fetishism, alien hand syndrome, ‘touch the truck’ endurance television, and thumb sucking as an addiction. However, it was while I was researching a previous blog on belly inflation fetishes that I came across a man who on the Yahoo! Answers website claimed he had a belly inflation fetish and a thumb fetish along with another person who responded saying he also shared the same fetish:

  • Extract 1: “Another weird fetish I have is ‘hitchhiker’s thumb’. Hitchhikers thumb is when the top part of your thumb bends backwards when pushed on or fully extended…The hitchhiker’s thumb fetish developed when I found out that my cousins could do it. I would ALWAYS ask questions about it and I would bend her thumbs back and forth for hours. And I just get turned on by it now…is this weird?” (Male, sexual orientation unknown)
  • Extract 2: “I [also] have a fetish for bendy thumbs hence the profile pic. It’s all good I say whatever turns u on and if not hurting anyone then it’s cool” (Male, sexual orientation unknown)

Although I have read about (i) thumb bondage (mentioned in a 2007 book chapter on themes of sadomasochistic expression by Dr. Charles Moser and Dr. Peggy Kleinplatz) and (ii) thumb sucking by adult babies that are into paraphilic infantilism, I had never read anything on standalone thumb fetishes. (I would also point out that the ‘thumb sucking’ is just one of many baby-like behaviours that paraphilic infantilists enjoy but do not necessarily see as a source of arousal in and of itself). There is also those who say that they engage is ‘thumb sex’ and defined by the online Urban Dictionary as when two people hold hands and run their thumbs around the other persons thumb or twiddle the thumbs”. There are also (for want of a better word) ‘cultural’ references to thumb fetishes such as the instrumental song ‘Mayor Oscar Goodman’s Thumb Fetish’ by US deathcore band Molotov Solution.


As far as I am aware there has never been any empirical research on thumb fetishism. There are various online websites and forums that feature individuals that claim to have very specific types of thumb fetishes. This is one of the more specific that I found:

  • Extract 3: “I’m a 34 year old men and I have thin thumbs (each ones have the same width as an American/Canadian penny, that’s 0.74 inch or 19 millimeters). I got a fetish that seems to be pretty rare. It consists of being turn on by comparing my thin thumbs with a woman that has larger ones than mine. Also, the younger the woman is with larger thumbs, the better. It’s pretty inoffensive, but rare I think” (Male heterosexual).

There are also whole webpages dedicated to the sexiness of thumb sucking. Here are some of the online accounts I found on the Thumb Sucking Adults website. They begin by noting that adult thumb sucking is “sexy. This fact shouldn’t be too surprising in that it involves the sensual oral center [and] so much of what is human has become sexualized in one way or another that thumb sucking adults is just another part of the total picture”. They then highlight some of their readers’ experiences:

  • Extract 3: “I am a bisexual woman who finds other women sucking their thumbs extremely erotic…First of all, growing up, I had a very close friend who lived down the street from me who also sucked her thumb. Experimenting with sex at a very early age…[she] and I would spend hours together exploring our bodies and touching each other. We learned how to masturbate and although I was so young, I discovered how to reach orgasm. I think perhaps Janice and I shared a certain closeness in our friendship and later in our intimacy because we both sucked our thumbs and felt accepted by each other if not by peers who seemed to ridicule us…I can summarize that my earliest, deepest feelings of sexual desire were connected to both thumb sucking and a female partner. Many years passed and I dated men here and there, but never quite felt emotionally or sexually fulfilled [as with women]…From the e-mails I’ve read on your site, I have also noticed that it is mostly the men who find thumbsucking erotic. Perhaps as a woman who is mostly gay and possesses some traits and attributes more commonly associated with men…I am more turned on by this than other women. And why does it turn me on? I’m sure it has to do with my childhood friend and the feelings associated with that particular behavior”(Bisexual female).
  • Extract 4: “The arousal that naturally occurs when I do it. Thumb in mouth…hand on penis. This goes way back. I had contributed an early ‘embarrassment’ to [another website] saying that I watched a home movie in front of all our relatives and there was this shot of me, around 3 years old, standing by the garage, thumb in mouth, hand holding crotch. I had never seen that before. There was devilish laughter. I laughed along, but was shocked. I do remember a dry climax sucking my thumb when I was about 6 or 7. And my first real emission at age 12 or 13 involved thumb sucking in my bed. So it is very ingrained in me. The physical feeling of doing it brings such erotic pleasure. When I first insert my thumb in my mouth, pressing it against my palate and rubbing it back and forth about 1/2″, the stimulus begins. I don’t suck continuously. I do it for 1-2 minutes and take my thumb out for about 20 seconds and then put it back in. Each time it gets better and better. The key thing is that my thumb gets wetter and softer and SMOOTHER against my palate. I am very curious if anyone else sucks their thumb this way. I don’t actually SUCK it. I rub it. The other important part is that as I rub it, my tongue proceeds to pulsate. It’s involuntary. There’s no stopping it as long as I connect with the right spot on my palate. This enhances the feeling greatly. This dual rubbing, pulsating action. My thumb would have to be cut off to stop me from doing it. The last part of sexuality in thumb sucking is observing others doing it. I have to be honest in saying that watching…is an immense turn-on. Fortunately, I know I can control my desires” (Heterosexual male)
  • Extract 5: “Larry finds many things attractive in a woman. One of these things, apparently, is that she sucks her thumb. It probably is not essential that she does so (if it was, we’d be talking more along the lines of a fetish) but, if she does suck her thumb, he finds that attractive, whatever the underlying psychodynamics. I propose that his preferences aren’t much different than, say, another man’s predilections for big-breasted women, though both allures aren’t necessarily exclusive…There are societal stigmas associated with the habit. Try sucking your thumb whenever you want to and you’ll see that at least an undue amount of attention will be focused your way for a while. The point is, perhaps as adult thumb sucking becomes more widely known, it is natural that some out there will find it an endearing quality in a person…For the adult thumb sucker, this site has been liberating…And, in the case of Larry, the fact that he has felt solitude in his thumb sucking, all his adult life, it’s certainly understandable to me that among all the feelings that are engendered when he sees it in another for the first time…[This website] simply proposes that adult thumb sucking is more common than otherwise assumed and should be accepted since it is, essentially, harmless and, for those that indulge, beneficial. As for thumb sucking being sexually provocative, I suppose that anything human can be sexualized by others eventually. As long as it’s legal, what’s wrong with that?” (Gender and sexual orientation unknown)
  • Extract 6: “I love adult women who still suck on their thumb. Since I was a kid, I felt an attraction for girls sucking their thumbs. My twin sister sucked her thumb till she was 16 years old! When I first started masturbating at age 12, I thought of a girl sucking her thumb. I’ve always looked for women that sucked their thumb and then ask them to suck it for me. When I was 18, I met a girl I suspected of still sucking her thumb. Strangely, I noticed she didn’t have any marks or callus on her thumb. But from time to time, I saw teeth marks and lipstick marks on her thumb…We started to have thumb sucking sex and I loved it. She liked it also. We stayed together four years. It became a habit. She’d suck her thumb for me and then I’d suck her thumb while we made love. I never sucked my thumb but now I suck my thumb while masturbating and thinking about my former girlfriend’s thumb or another girl’s thumb. I always look for women sucking their thumbs in their cars while driving. I have seen three in all the years I have looked. Those times were awesome. I never tried to make contact. I am married now, but my wife never sucks her thumb. She will do it if I ask her, but that isn’t the same. I like it when an adult woman does it naturally…I love a woman with a thumb callus and nice teeth (there are a few). I love to see a wet thumb. I like it when an adult sucks her thumb with the index finger over the nose. I find that very sexy” (Heterosexual male).
  • Extract 7: I find thumb sucking sensual, sexual, erotic, comforting, calming…It’s like catching someone at their most vulnerable. Partly because of its social taboo, it can even be slightly ‘naughty’…But it is an exciting thought to me to perhaps one day ‘catch’ someone else thumb sucking. Thumb sucking provides sensations around the mouth and nose that can be reproduced during sex or loveplay, although thumb sucking is less tiring. It feels nice, smells nice, tickles [the] pleasure centers. It provides the sensations of skin-to-skin warmth that I think everyone of us craves…It’s sensual, it’s intimate. But it’s also sensual and sexual. I find myself sucking my thumb after sex much like I might grab for a cigarette…But I think that thumb sucking is by far more satisfying and truly far less addicting [than smoking]. And definitely far less damaging…Quite honestly I didn’t find out how much I found finger and thumb sucking an exciting part of foreplay and sex until I was 23” (Heterosexual female).
  • Extract 8: I suck my thumb for the usual reasons, tension relief, to go to sleep, it feels good. But, I notice that other contributors here suck their thumb because it also feels erotic, and, I have to say, I agree…When I’m aroused, it enhances the feeling so much more. So it’s obvious that I’ve learned to associate my thumb sucking with something sexual…When I look at the photos of women at this site, sucking away, I just find them so beautiful, so sexually enthralling….First off, there’s the lips. I think most people can understand why lips can be very erotic. I don’t want to get into heavy psychology, but, let’s face it, lips are sexy, especially full lips, parted ever so slightly. They’re like an invitation to something exciting…When I see a woman’s full lips open just a bit, my tongue gets an irresistible urge to explore her sweet mouth…If her teeth were affected by thumb sucking, all the better. The thought that she can’t stop her habit, and the pleasure she derives from it, even if her teeth are affected to the point of obvious buckedness adds that much more to my sensation…She looks like something innocent, childlike but not a child. Her profile, exaggerating her now protrusive lips, wrapped around a phallus-like object that is her compulsion, her requirement, her urgency…I want her thumb to feel comfortable in my mouth as I experience, once again, her essence, her habit as mine” (Heterosexual male).

Obviously this is just a small selection of online accounts of sexual thumb sucking I have come across and I can’t know for sure that they are genuine (but they appear that way to me). Also, I have no idea whether these are typical but I can make a few tentative conclusions. Firstly, both males and females can find thumb sucking sexually stimulating. Secondly, sexual thumb suckers tend to be heterosexual (although one account was from a bisexual woman). Thirdly, most experiences of sexual thumb sucking are rooted in childhood experiences and that the acquisition and development of such behaviour is related with associative pairing (i.e., classical conditioning). Fourthly, no-one pathologizes the behaviour, and as long as the act is consensual, there is absolutely nothing wrong with the behaviour as a sexual preference. Finally, none of the accounts suggest the sexual thumb sucking is fetishistic – just that it is a non-normative sexual expression that fits alongside their other sexual experiences.

While researching this article I also came across the remarkable story of American Rafe Briggs (from Oakland, California) in a 2013 issue of the International Business Times. In 2004, Biggs fell off a roof and broke his neck leaving him paralyzed from the chest down. He obviously thought he would never experience any kind of sexual pleasure again but he was wrong:

“Turns out he can. Biggs, 43, says that his thumb is his ‘surrogate penis’, and that he gets ‘orgasmic sensations’ whenever it’s stimulated. ‘I never thought it would be possible, but massaging and sucking on my thumb, feels a lot like my penis used to feel – it’s really hot” said Biggs, whose girlfriend helped him discover this phenomenon a year after the accident. Sex therapists like Lisa Skye Carle, who works with Biggs, calls it a ‘transfer orgasm – where another place on the body gives the same sensation”. Biggs has made it his mission to helping quadriplegics lead sexually fulfilling lives, working with the group ‘Sexability’ an ‘organization committed to empowering people with disabilities to explore sexuality and creating intimate loving relationships. Since our beginning in 2006, we have been working with individuals, groups and organizations to transform sexuality and disability’. ”

Surprise, surprise: A brief overview of our recent papers on strange addictions and behaviours

Following my recent blogs where I outlined some of the papers that my colleagues and I have published on mindfulness, Internet addiction, gaming addiction, youth gambling, workaholism, exercise addiction, and sex addiction, here is a round-up of recent papers that my colleagues and I have published on strange and/or surprising addictions and behaviours.

Foster, A.C., Shorter, G.W. & Griffiths, M.D. (2015). Muscle Dysmorphia: Could it be classified as an Addiction to Body Image? Journal of Behavioral Addictions, 4, 1-5.

  • Background: Muscle dysmorphia (MD) describes a condition characterised by a misconstrued body image in which individuals who interpret their body size as both small or weak even though they may look normal or highly muscular. MD has been conceptualized as a type of body dysmorphic disorder, an eating disorder, and obsessive–compulsive disorder symptomatology. Method and aim: Through a review of the most salient literature on MD, this paper proposes an alternative classification of MD – the ‘Addiction to Body Image’ (ABI) model – using Griffiths (2005) addiction components model as the framework in which to define MD as an addiction. Results: It is argued the addictive activity in MD is the maintaining of body image via a number of different activities such as bodybuilding, exercise, eating certain foods, taking specific drugs (e.g., anabolic steroids), shopping for certain foods, food supplements, and the use or purchase of physical exercise accessories). In the ABI model, the perception of the positive effects on the self-body image is accounted for as a critical aspect of the MD condition (rather than addiction to exercise or certain types of eating disorder). Conclusions: Based on empirical evidence to date, it is proposed that MD could be re-classified as an addiction due to the individual continuing to engage in maintenance behaviours that may cause long-term harm.

Griffiths, M.D., Foster, A.C. & Shorter, G.W. (2015). Muscle dysmorphia as an addiction: A response to Nieuwoudt (2015) and Grant (2015). Journal of Behavioral Addictions, 4, 11-13.

  • Background: Following the publication of our paper ‘Muscle Dysmorphia: Could it be classified as an addiction to body image?’ in the Journal of Behavioral Addictions, two commentaries by Jon Grant and Johanna Nieuwoudt were published in response to our paper. Method: Using the ‘addiction components model’, our main contention is that muscle dysmorphia (MD) actually comprises a number of different actions and behaviors and that the actual addictive activity is the maintaining of body image via a number of different activities such as bodybuilding, exercise, eating certain foods, taking specific drugs (e.g., anabolic steroids), shopping for certain foods, food supplements, and purchase or use of physical exercise accessories. This paper briefly responds to these two commentaries. Results: While our hypothesized specifics relating to each addiction component sometimes lack empirical support (as noted explicitly by both Nieuwoudt and Grant), we still believe that our main thesis (that almost all the thoughts and behaviors of those with MD revolve around the maintenance of body image) is something that could be empirically tested in future research by those who already work in the area. Conclusions: We hope that the ‘Addiction to Body Image’ model we proposed provides a new framework for carrying out work in both empirical and clinical settings. The idea that MD could potentially be classed as an addiction cannot be negated on theoretical grounds as many people in the addiction field are turning their attention to research in new areas of behavioral addiction.

Maraz, A., Király, O., Urbán, R., Griffiths, M.D., Demetrovics, Z. (2015). Why do you dance? Development of the Dance Motivation Inventory (DMI). PLoS ONE, 10(3): e0122866. doi:10.1371/ journal.pone.0122866

  • Dancing is a popular form of physical exercise and studies have show that dancing can decrease anxiety, increase self-esteem, and improve psychological wellbeing. The aim of the current study was to explore the motivational basis of recreational social dancing and develop a new psychometric instrument to assess dancing motivation. The sample comprised 447 salsa and/or ballroom dancers (68% female; mean age 32.8 years) who completed an online survey. Eight motivational factors were identified via exploratory factor analysis and comprise a new Dance Motivation Inventory: Fitness, Mood Enhancement, Intimacy, Socialising, Trance, Mastery, Self-confidence and Escapism. Mood Enhancement was the strongest motivational factor for both males and females, although motives differed according to gender. Dancing intensity was predicted by three motivational factors: Mood Enhancement, Socialising, and Escapism. The eight dimensions identified cover possible motives for social recreational dancing, and the DMI proved to be a suitable measurement tool to assess these motives. The explored motives such as Mood Enhancement, Socialising and Escapism appear to be similar to those identified in other forms of behaviour such as drinking alcohol, exercise, gambling, and gaming.

  • Although recreational dancing is associated with increased physical and psychological well-being, little is known about the harmful effects of excessive dancing. The aim of the present study was to explore the psychopathological factors associated with dance addiction. The sample comprised 447 salsa and ballroom dancers (68% female, mean age: 32.8 years) who danced recreationally at least once a week. The Exercise Addiction Inventory (Terry, Szabo, & Griffiths, 2004) was adapted for dance (Dance Addiction Inventory, DAI). Motivation, general mental health (BSI-GSI, and Mental Health Continuum), borderline personality disorder, eating disorder symptoms, and dance motives were also assessed. Five latent classes were explored based on addiction symptoms with 11% of participants belonging to the most problematic class. DAI was positively associated with psychiatric distress, borderline personality and eating disorder symptoms. Hierarchical linear regression model indicated that Intensity (ß=0.22), borderline (ß=0.08), eating disorder (ß=0.11) symptoms, as well as Escapism (ß=0.47) and Mood Enhancement (ß=0.15) (as motivational factors) together explained 42% of DAI scores. Dance addiction as assessed with the Dance Addiction Inventory is associated with indicators of mild psychopathology and therefore warrants further research.


Greenhill, R. & Griffiths, M.D. (2015). Compassion, dominance/submission, and curled lips: A thematic analysis of dacryphilic experience. International Journal of Sexual Health, 27, 337-350.

  • Objectives: Dacryphilia is a non-normative sexual interest that involves enjoyment or arousal from tears and crying, and to date has never been researched empirically. The present study set out to discover the different interests within dacryphilia and explore the range of dacryphilic experience. Methods: A set of online interviews were carried out with individuals with dacryphilic preferences and interests (six females and two males) from four countries. The data were analyzed for semantic and latent themes using thematic analysis. Results: The respondents’ statements focused attention on three distinct areas that may be relevant to the experience of dacryphilia: (i) compassion; (ii) dominance/submission; and (iii) curled-lips. The data provided detailed descriptions of features within all three interests, which are discussed in relation to previous quantitative and qualitative research within emotional crying and tears, and the general area of non-normative sexual interests. Conclusions: The study suggests new directions for potential research both within dacryphilia and with regard to other non-normative sexual interests.

  • Aims: Recent research has suggested that for some individuals, educational studying may become compulsive and excessive and lead to ‘study addiction’. The present study conceptualized and assessed study addiction within the framework of workaholism, defining it as compulsive over-involvement in studying that interferes with functioning in other domains and that is detrimental for individuals and/or their environment. Methods: The Bergen Study Addiction Scale (BStAS) was tested — reflecting seven core addiction symptoms (salience, mood modification, tolerance, withdrawal, conflict, relapse, and problems) — related to studying. The scale was administered via a cross-sectional survey distributed to Norwegian (n = 218) and Polish (n = 993) students with additional questions concerning demographic variables, study-related variables, health, and personality. Results: A one-factor solution had acceptable fit with the data in both samples and the scale demonstrated good reliability. Scores on BStAS converged with scores on learning engagement. Study addiction (BStAS) was significantly related to specific aspects of studying (longer learning time, lower academic performance), personality traits (higher neuroticism and conscientiousness, lower extroversion), and negative health-related factors (impaired general health, decreased quality of life and sleep quality, higher perceived stress). Conclusions: It is concluded that BStAS has good psychometric properties, making it a promising tool in the assessment of study addiction. Study addiction is related in predictable ways to personality and health variables, as predicted from contemporary workaholism theory and research.

  • Background and aims: ‘Study addiction’ has recently been conceptualized as a behavioral addiction and defined within the framework of work addiction.  Using a newly developed measure to assess this construct, the Bergen Study Addiction Scale (BStAS), the present study examined the one-year stability of study addiction and factors related to changes in this construct over time, and is the first longitudinal investigation of study addiction thus far. Methods: The BStAS and the Ten Item Personality Inventory (TIPI) were administered online together with questions concerning demographics and study-related variables in two waves. In Wave 1, a total of 2,559 students in Norway and 2,177 students in Poland participated. A year later, in Wave 2, 1,133 Norwegians and 794 Polish who were still students completed the survey. Results: The test-retest reliability coefficients for the BStAS revealed that the scores were relatively stable over time. In Norway scores on the BStAS were higher in Wave 2 than in Wave 1, while in Poland the reverse pattern was observed. Learning time outside classes at Wave 1 was positively related to escalation of study addiction symptoms over time in both samples. Being female and scoring higher on neuroticism were related to an increase in study addiction in the Norwegian sample only. Conclusion: Study addiction appears to be temporally stable, and the amount of learning time spent outside classes predicts changes in study addiction one year later.

To pee or not to pee? Another look at paraphilic behaviours

Strange, bizarre and unusual human sexual behaviour is a topic that fascinates many people (including myself of course). Last week I got a fair bit of international media coverage being interviewed about the allegations that Donald Trump hired women to perform ‘golden showers’ in front of him (i.e., watching someone urinate for sexual pleasure, typically referred to as urophilia). I was interviewed by the Daily Mirror (and many stories used my quotes in this particular story for other stories elsewhere). I was also commissioned to write an article on the topic for the International Business Times (and on which this blog is primarily based). The IBT wanted me to write an article on whether having a liking for strange and/or bizarre sexual preferences makes that individual more generally deviant.


Although the general public may view many of these behaviours as sexual perversions, those of us that study these behaviours prefer to call them paraphilias (from the Greek “beyond usual or typical love”). Regular readers of my blog will know I’ve written hundreds of articles on this topic. For those of you who have no idea what parahilias really are, they are uncommon types of sexual expression that may appear bizarre and/or socially unacceptable, and represent the extreme end of the sexual continuum. They are typically accompanied by intense sexual arousal to unconventional or non-sexual stimuli. Most adults are aware of paraphilic behaviour where individuals derive sexual pleasure and arousal from sex with children (paedophilia), the giving and/or receiving of pain (sadomasochism), dressing in the clothes of the opposite sex (transvestism), sex with animals (zoophilia), and sex with dead people (necrophilia).

However, there are literally hundreds of paraphilias that are not so well known or researched including sexual arousal from amputees (acrotomophilia), the desire to be an amputee (apotemnophilia), flatulence (eproctophilia), rubbing one’s genitals against another person without their consent (frotteurism), urine (urophilia), faeces (coprophilia), pretending to be a baby (infantilism), tight spaces (claustrophilia), restricted oxygen supply (hypoxyphilia), trees (dendrophilia), vomit (emetophilia), enemas (klismaphilia), sleep (somnophilia), statues (agalmatophilia), and food (sitophilia). [I’ve covered all of these (and more) in my blog so just click on the hyperlinks of you want to know more about the ones I’ve mentioned in this paragraph].

It is thought that paraphilias are rare and affect only a very small percentage of adults. It has been difficult for researchers to estimate the proportion of the population that experience unusual sexual behaviours because much of the scientific literature is based on case studies. However, there is general agreement among the psychiatric community that almost all paraphilias are male dominated (with at least 90% of all those affected being men).

One of the most asked questions in this field is the extent to which engaging in unusual sex acts is deviant? Psychologists and psychiatrists differentiate between paraphilias and paraphilic disorders. Most individuals with paraphilic interests are normal people with absolutely no mental health issues whatsoever. I personally believe that there is nothing wrong with any paraphilic act involving non-normative sex between two or more consenting adults. Those with paraphilic disorders are individuals where their sexual preferences cause the person distress or whose sexual behaviour results in personal harm, or risk of harm, to others. In short, unusual sexual behaviour by itself does not necessarily justify or require treatment.

The element of coercion is another key distinguishing characteristic of paraphilias. Some paraphilias (e.g., sadism, masochism, fetishism, hypoxyphilia, urophilia, coprophilia, klismaphilia) are engaged in alone, or include consensual adults who participate in, observe, or tolerate the particular paraphilic behaviour. These atypical non-coercive behaviours are considered by many psychiatrists to be relatively benign or harmless because there is no violation of anyone’s rights. Atypical coercive paraphilic behaviours are considered much more serious and almost always require treatment (e.g., paedophilia, exhibitionism [exposing one’s genitals to another person without their consent], frotteurism, necrophilia, zoophilia).

For me, informed consent between two or more adults is also critical and is where I draw the line between acceptable and unacceptable. This is why I would class sexual acts with children, animals, and dead people as morally and legally unacceptable. However, I would also class consensual sexual acts between adults that involve criminal activity as unacceptable. For instance, Armin Meiwes, the so-called ‘Rotenburg Cannibal’ gained worldwide notoriety for killing and eating a fellow German male victim (Bernd Jürgen Brande). Brande’s ultimate sexual desire was to be eaten (known as vorarephilia). Here was a case of a highly unusual sexual behaviour where there were two consenting adults but involved the killing of one human being by another.

Because paraphilias typically offer pleasure, many individuals affected do not seek psychological or psychiatric treatment as they live happily with their sexual preference. In short, there is little scientific evidence that unusual sexual behaviour makes you more deviant generally.

Come undone: The strange case of the ‘ejaculate fetishist’

In a previous blog I briefly examined semen fetishes and the acts of ‘bukkake’ (most commonly seen in hard core pornographic films where a group of men all simultaneously ejaculate over a women or man), and ‘gokkun’ (where a man or woman consumes the semen of one or more men from a drinking receptacle, e.g., cups, glasses, beakers, etc.). In that article I noted that while there is a fair amount of (non-academic) literature about bukkake, references to semen fetishes appear to be rare with nothing published in academic journals.

However, since writing that article, a case study of a 39-year old man with an ‘ejaculate fetish’ was published in the Journal of Psychiatry by three Turkish medics (Dr. Safak Taktak, Dr. Mustafa Karakus and Dr. Salih Murat Eke) –  ‘The Man Whose Fetish Object is Ejaculate: A Case Report’. (In fact, Dr. Taktak has published a number of interesting case studies of paraphilic behaviour including shoe fetishism and paraphilias more generally [see ‘Further reading’ below]). Following a crime of molestation, the man had been arrested by Turkish police. (In fact, it turned out the man had already spent 10 years in prison for armed robbery when he was in his twenties and was released from jail when he was 31 years old).


The judicial authorities demanded that the man had to undergo a psychiatric assessment because one of his behaviours was the buying of ejaculate from young men that he would then smear on his genitals for sexual satisfaction. The act of smearing semen on his body had begun in prison when he would smear semen on bodily wounds and provided (presumably therapeutic) relief (as the prison did not provide medicine or cream for bodily injuries). The paper also claimed that the act of taking semen from each other and applying it to wounds and sores was commonplace in the prison he was at. Following his release from prison, he continued the habit and “became obsessed with it and he bought semen from different people on a monthly basis and spread it on the genital area”. Fifteen days prior to his psychiatric assessment, he was accused of molesting a 16-year old adolescent while trying to buy semen from him. The adolescent was reported as saying:

“A man held my arm and said that he had a job for me and he would give money if I do that job. I told him if I can do, I would do. He said he would be there [an hour and a half] later, and told me to find him. After he came, he told me that he buys human sperm, and asked me if I give him sperm, which surprised me a lot. Then he took three or four plastic bags out of the pocket of his jacket full of white things. He said these bags are the sperms that he bought from three or four kids. In exchange of sperm, he gave things like money, stereos and televisions”.

The adolescent’s father found out what had happened to his son and caught the man who had wanted his son’s semen. The man told the father that he wanted the semen to alleviate itchiness. During the psychiatric examination by the authors, the man was described as having mildly depressive emotions, natural psychomotor activity, sufficient cognitive function, and no delusions and/or hallucinations. He also had a history of alcohol and marijuana abuse (but since leaving prison he had stopped abusing these substances). Using the Minnesota Multiphasic Personality Inventory (MMPI) the authors said he had inconsistent behaviour, difficulty in controlling his impulses, was angry and short tempered, displayed antisocial behaviour, was sexually deviant, had obsessive sexual thoughts, was socially isolated, and had a negative self-perception. They also wrote that his psychological profile suggested an antisocial or schizoid personality disorder.

The paper also noted that his father has also been in prison on a number of occasions, and that his mother and her relatives looked after him and his younger brother, and that they had “a hard life” while growing up. From the age of 11-12 years old, he started masturbating regularly (sometimes a few times a day). During early adolescence he began engaging in frotteurism (rubbing his genitals up against other people) particularly on bus journeys. Now, as a man, he claimed he could not masturbate without the use of other people’s semen. He began buying other individuals’ semen when he got out of prison (“from 30 young men in exchanges for money”) and always carried semen with him wherever he went.

The authors noted that unlike most other fetishes, the sexualisation of semen as a fetish did not occur until he was in prison (i.e., adulthood rather than childhood or adolescence). I’m not sure why (based on the evidence in the paper) but they also speculated that the man’s semen fetish was used to overcome low self-esteem and a sense of failure” and that the fetish behaviour “occurred from a trauma caused by the bad attitude of [his] parents at an early age, and [that] such negative experiences contributed to the emergence of fetish behavior”. The paper also claimed that: “He discovered the fetish object to deal with the anger for the negative events he faced when he was in prison for ten years for armed robbery. Impulse control is likely to be impaired because of the adverse conditions created by the prison”.

They also described the man’s semen fetish as a “mental illness” (in fact, the paper seemed to imply that all fetishes are mental illnesses which is clearly not the case as most non-normative sex is non-problematic for those engaging in such behaviour). However, by diagnosing the man has having a mental illness, it meant that he was not mentally competent enough to stand trial. The paper concluded that:

“In our case, the number of [victims] is few, but [our patient is] respectively harmless to the victims and not dangerous. He cannot control his urges and behaviors.
