Nailed it: A brief look at onychophilia

In a previous blog, I looked at fingernail fetishism. Since writing that article, I’ve had a few individuals get in touch with me to say that they had very specific fingernail fetishes (such as a keen interest in very long nails). As the Kinkly website notes:

“A fingernail fetish can hinge on the nail color, texture, or length. If the fetish hinges on long nails, the fetish is sometimes referred to as onychophilia. For the fingernail fetishist the excitement is in the details, so nail art is given special attention”.

However, a really short article on ‘Lady Zombie’s World of Pain, Pleasure and Sin’ website also notes that onychophilia as a fingernail fetish but says it only refers to long nails (rather than nails more generally):

“Onychophilia is a fetish for extremely long nails (either real or fake) and/or painted fingernails. As with all fetishes, preferences vary! While some fetishists say, ‘The longer, the better,’ many others find them to be repulsive after a certain length”.

In my previous article I mentioned the the only specific case of fingernail fetishism that I found in the academic literature was a 1972 paper in the American Journal of Clinical Hypnosis, by Dr. Austin McSweeny who successfully treated a young male fingernail fetishist using hypnosis (although other sexologists such as Willem Stekel and Martin Kafka had mentioned such a fetish in passing). The same case study was cited by Dr. Jesse Baring in a blog on fingernail fetishism for Scientific American. He noted:

“He could [only] become sexually aroused and experience penile erection by seeing or fantasizing the fingernails of a woman as they were being bitten by her. Occasionally, the mere sight of a woman’s severely bitten fingernails would cause the patient to experience a spontaneous erection … When the patient experienced the proper fetish situation, he could masturbate to the point of ejaculation and experience gratification. This was his only means of expressing his sex drive…The psychotherapist’s request for the man to picture heterosexual intercourse or a vagina in his mind’s eye was enough to make him vomit”.

A 2019 article by Stephen Alexander (‘Onychophilia: Two types of nail fetish’) notes that fingernail fetishes are subsumed within ‘hand partialism’ (which can arguably include other fetishes I have examined including ‘handwear fetishism’ and ‘hands on hips fetishism’). Alexander asserts:

“I think that [fingernail fetishism] deserves critical attention in its own right. For the nails are not like any other part of the hand in that they are not composed of living material; they are made, rather, of a tough protective protein called alpha-keratin. D. H. Lawrence [in his 1963 essay ‘Why the novel matters’] describes his fingernails as ‘ten little weapons between me and an inanimate universe, they cross the mysterious Rubicon between me alive and things […] which are not alive, in my own sense’. Thus, I think there’s something in the claim that what nail (and hair) fetishists are ultimately aroused by is death; that they are, essentially, soft-core necrophiles. Having said that, the human nail as a keratin structure (known as an unguis) is closely related to the claws and hooves of other animals, so I suppose one could just as legitimately suggest a zoosexual origin to the love of fingernails”.

To support his claim that fingernail fetishists are “soft-core necrophiles”, Alexander noted that there had been a recorded case in the 1963 book Perverse Crimes in History: Evolving concepts of sadism, lust-murder, and necrophilia – from ancient to modern times (by R.E.L. Masters and Eduard Lee) where “an illicit lover derived pleasure from eating the nail trimmings of corpses (necro-onychophagia), thereby lending support to the theory that nail fetishism has a far darker and more ghoulish undercurrent”.

I also learned in Alexander’s article that there is another related paraphilia – amychophilia – which refers to sexual arousal from being scratched (or as Alexander puts it: “a love of the pain [fingernails] can inflict, when grown long and sharp”). I went and checked if amychophilia was in my ‘go to’ book on paraphilias (i.e., Dr. Anil Aggrawal’s Forensic and Medico-legal Aspects of Sexual Crimes and Unusual Sexual Practices) – and it was. Dr. Aggrawal defines amychophilia as “deriving sexual pleasure from being scratched” which technically could mean sexual arousal from being scratched by things other than fingernails (e.g., toenails, back-scratcher) although scratching for most people will be synonymous with fingernail scratching. Given these definitions, I would argue that amychophilia is more akin to masochism than onychophilia because the root of amychophilia is in the feeling provided rather than what is doing the scratching. Alexander also quotes at length from Daphne du Maurier’s short story ‘The Little Photographer’ (from The Birds and Other Stories) and says that one scene in the book describes onychophilia in “fetishistic detail”. (I won’t reproduce it here but you can check it out in Alexander’s online article here).

Which brings me to the final article I came across on onychophilia by Liz Lapont on The Naked Advice website. She was writing in response to an email she had received:

“I’m a guy with a sexual fetish for long fingernails (not too long, usually the length that people get when they get their nails done). I beat off to pictures of nails and I have conversations with female friends about their nails. I wanted to know if you can make a video about this type of fetish. Seeing as not a lot of people talk about or show interest in this fetish, am I weird?”

Lapont replies that the fetish is both atypical and uncommon but not weird (“as in creepy and in need of psychiatric help”). My own take is that this is a non-normative sexual behaviour but agree with Lapont that there is nothing to worry about if the behaviour causes no problems in the individuals’ lives. She concludes by saying:

“Consult any list of the most common sexual fetishes and nails don’t crack the top 10. However it’s not unheard of, and toenails are often an associated turn-on for men with a fetish for feet. The clinical term for a fingernail fetish is onychophilia. For some, it’s the act of biting the fingernails that turn them on. For others, it might be their extreme length that is most erotic. Hands and nails play a big role even during the most vanilla sex in the world…So it’s not a stretch to see how for some men, fixating on fingernails would be IT for them”.

Displeasures of the flesh: A brief look at anthropophagolagnia and paraphilic behaviour in serial killers

In previous blogs I have examined the psychology of sexual cannibalism and erotophonophilia (aka ‘lust murder’) as well as an article that I wrote on serial killers that collect their victims’ body parts as ‘trophies’. One very rare sub-type of both sexual cannibalism and erotophonophilia is anthropophagolagnia. This particular type of sexual paraphilia has been defined by Dr Anil Aggrawal as the paraphilia of “rape with cannibalism” and by the Right Diagnosis website as “sexual urges, preferences or fantasies involving raping and then cannibalizing the victim”.

The Listaholic website goes as far to say that anthropophagolagnia is one of the ten “most bizarre sexual fetishes on earth” claiming that serial killer is the “poster boy” for these “twisted” individuals. Other serial killers that might be classed as anthropophagolagniacs include Albert Fish, Peter Kirsten, Ottis Toole and Ed Gein. However, there also appear to be cases of what I would call ‘systematic anthropophagolagnia’ if the extract I found online is true:

“While it is easy to dismiss one case as stemming from some sort of neurological aberrations in the participants, we also see sexualized cannibalism in modern day Africa. In the early 2000s in Congo, rape and cannibalism were reported to coincide sporadically across the region. The claims are backed by a UN investigation into the phenomena…Rebels would go into villages and rape the women and children, then dismember them alive while eating their flesh. There are many reports of family members being forced to eat the flesh of other murdered family members after being raped…The men committing these atrocities do not have any neurological aberrations, they simply have the power to exercise this behavior. While cannibalism has been practiced in Africa as part of spiritual traditions for centuries, sadistic sexualized torture is not part of that tradition. So why add it in? Presumably the rebels didn’t all happen to be born child rapists either, yet raping children is part of their terror campaign and they must be able to achieve an erection to carry out the task, and so it must be assumed they learned to like it”.

Last year, I also read about 40-year old preacher Stephen Tari, the leader of a 6,000-strong cannibal rape cult in Papua New Guinea. He was in prison following his conviction for a brutal rape but escaped (only to be killed by people from his village in retaliation for the cannibalistic rape murders he had committed). As a report in The Independent noted:

“[Tari] had previously been accused of raping, murdering and eating three girls in front of their traumatised mothers…The charismatic cult leader, who wore white robes and is said to have regularly drunk the blood of his ‘flower girls’, quickly returned to his home village of Gal after [a prison] escape, but could only manage six months before killing yet again…It has not yet been established if the murdered woman was killed as part of a blood sacrifice, but it is considered likely as Tari was said to have been attempting to resurrect his cult following the spell in prison”.

Dr. Eric Hickey (in his book Serial Murderers and Their Victims) notes that paraphilic behaviour is very common among those that commit sexual crimes (and that more than one is often present) but that the two activities (sex offending and paraphilias) may be two independent constructs and that one does not necessarily affect the other. In fact he notes that:

“Rather than paraphilia being caused by sexual pathology, they may be better understood as one of many forms of general social deviance…For the male serial killer, the paraphilia engaged in usually has escalated from softer forms to those that are considered not only criminal but violent as well. They range from unusual to incredibly bizarre and disgusting. As paraphilia develop, men affected by them often engage in several over a period of time. Most men who engage in paraphilia often exhibit three or four different forms, some of them simultaneously. For those with violent tendencies, soft paraphilia can quickly lead to experimentation with hardcore paraphilia that often involves the harming of others in sexual ways. For example, some paraphilic offenders prefer to stalk and sexually assault their victims in stores and other public places without getting caught. The thrill of hunting an unsuspecting victim contributes to sexually arousing the offender”.

Hickey asserts that anthropophagolagnia is one of the so-called ‘attack paraphilias’ (as opposed to the ‘preparatory paraphilias’). Attack paraphilias are described by Hickey as being sexually violent (towards other individuals including children in extreme circumstances). Preparatory paraphilias are defined by Hickey as those “that have been found as part of the lust killer’s sexual fantasies and activities” (including those that display anthropophagolagnia). However, Hickey notes that individuals that engage in preparatory paraphilias do not necessarily go on to become serial killers. He then goes on to say:

“The process of sexual fantasy development may include stealing items from victims. Burglary, although generally considered to be a property crime, also is sometimes a property crime for sexual purposes. Stealing underwear, toiletries, hair clippings, photographs, and other personal items provides the offender with souvenirs for him to fantasize over”.

Some of the examples Hickey cites are both revealing and psychologically interesting:

“One offender noted how he would climax each time he entered a victim’s home through a window. The thought of being alone with people sleeping in the house had become deeply eroticized. Another offender likes to break into homes and watch victims sleep. He eventually will touch the victim and will only leave when she begins to scream. He ‘began’ his sexual acting out as a voyeur. This paraphilic process was also examined by Purcell and Arrigo (2001), who note that the process consists of mutually interactive elements: paraphilic stimuli and fantasy; orgasmic conditioning process; and facilitators (drugs, alcohol, and pornography). The probability of the offender harming a victim is extremely high given the progressive nature of his sexual fantasies”.

Along with anthropophagolagnia, other ‘attack paraphilias’ that have been associated with serial killers include amokoscisia (sexual arousal or sexual frenzy from a desire to slash or mutilate other individuals [typically women]), anophelorastia (sexual arousal from defiling or ravaging another individual), biastophilia (sexual arousal from violently raping other individuals; also called raptophilia), dippoldism (sexual arousal from abusing children, typically in the form of spanking and corporal punishment), necrophilia (sexual arousal from having sex with acts with dead individuals), paedophilia (sexual arousal from having sex with minors typically via manipulation and grooming), and sexual sadism (empowerment and sexual arousal derived from inflicting pain and/or injuring other individuals).

The ‘preparatory paraphilias’ that typically precede serial killing and attack paraphilias such as anthropophagolagnia include agonophilia (sexual arousal caused by a sexual partner pretending to struggle), altocalciphilia (sexual arousal from high-heeled shoes), autonecrophilia (sexual arousal by imagining oneself as a dead person), exhibitionism (exposing genitals to inappropriate and/or non-consenting people for sexual arousal), frottage (sexual arousal from rubbing up against the body against a sexual partner or object), gerontophilia (sexual arousal from someone whose age is older and that of a different generation), hebephilia (men that are sexually aroused by aroused by teenagers), kleptolagnia (sexual arousal from stealing), retifism (sexual arousal from shoes), scatophilia (sexual arousal via making telephone calls, using vulgar language, and/or trying to elicit a reaction from the other party), scoptophilia (sexual arousal by watching others [typically engaged in sexual behaviour] without their consent, and more usually referred to as voyeurism), and somnophilia (sexual arousal from fondling strangers in their sleep). The multiplicity of co-existent paraphilias (including anthropophagolagnia) is highlighted by the Wikipedia entry on Jeffrey Dahmer:

“Dahmer readily admitted to having engaged in a number of paraphilic behaviors, including necrophilia, exhibitionism, hebephilia, fetishism, pygmalionism, and erotophonophilia. He is also known to have several partialisms, including anthropophagy (also known as cannibalism). One particular focus of Dahmer’s partialism was the victim’s chest area. By his own admission, what caught his attention to Steven Hicks hitchhiking in 1978 was the fact the youth was bare-chested; he also conceded it was possible that his viewing the exposed chest of Steven Tuomi in 1987 while in a drunken stupor may have led him to unsuccessfully attempt to tear Tuomi’s heart from his chest. Moreover, almost all the murders Dahmer committed from 1990 onwards involved a ritual of posing the victims’ bodies in suggestive positions – many pictures taken prior to dismemberment depict the victims’ bodies with the chest thrust outwards. Dahmer also derived sexual pleasure from the viscera of his victims; he would often masturbate and ejaculate into the body cavity and at other times, literally used the internal organs as a masturbatory aid”.

Almost nothing is known empirically about anthropophagolagnia except that it is very rare and that almost all information about it comes from serial killers that have been caught. Explanations for the development of anthropophagolagnia can only be speculated but are likely to be no different from the development of other paraphilic behaviour. Hickey (citing Irwin Sarason and Barbara Sarason’s Abnormal Psychology textbook) notes five key explanations for the development of paraphilias (reproduced below verbatim):

• Psychodynamic – paraphilic behavior as a manifestation of unresolved conflicts during psychosexual development;
• Behavioral – paraphilia is developed through conditioning, modeling, reinforcement, punishment, and rewards, the same process that normal sexual activity is learned;
• Cognitive – paraphilia become substitutes for appropriate social and sexual functioning or the inability to develop satisfying marital relationships;
• Biological – heredity, prenatal hormone environment, and factors contributing to gender identity can facilitate paraphilic interests. Other explanations are linked to brain malfunctioning and chromosomal abnormalities;
• Interactional – that development of paraphilia is a process that results from psychodynamic, behavioral, cognitive, and biological factors.

As an eclectic, I favour the interactional explanation for the existence of anthropophagolagnia but also believe that the most important influences are the behavioural aspects via classical and operant conditioning processes.
