Tickled pink: A brief look at knismolagnia

“My friend’s sister always asked me to tickle her, and I would. Then one day I was tickling her and she climaxed and kissed me. It freaked me out because I wasn’t tickling near her private parts. I thought that maybe it was a one time thing, so I tickled her two more times on different occasions, and she climaxed both times” (posting on the ‘Is It Normal?’ website)

There are hundreds of sexual paraphilias of which little is known. One of the most obscure paraphilias but which is definitely known to exist is knismolagnia. According to Dr. Anil Aggrawal in his 2009 book Forensic and Medico-legal Aspects of Sexual Crimes and Unusual Sexual Practices, knismophilia is a sexual paraphilia in which individuals derive sexual pleasure and arousal from tickling or being tickled (and is also known as titillagnia). The Right Diagnosis website claims the symptoms of knismolagnia are (i) sexual arousal gained from being tickled, (ii) sexual interest in tickling, (iii) recurring intense sexual urges involving tickling, and (iv) sexual arousal associated with tickling. A knismolagnia article on another online site (Gay Fetish Goth) claims that different individuals may find tickling of virtually any region of the body to be pleasurable, and that knismolagnia can also involve sexual arousal from simply watching others being tickled. The same article also noted (but without any supporting evidence) that:

“However, people who claim to have a tickling fetish are likely to enjoy this activity to the exclusion of other pre-sex activities. For some, the focus is entirely on the tickling, with full intercourse less important or not included at all. People whose sexuality is based almost solely on tickling can be said to have a tickling fixation. This fixation may also exist outside of sexual contexts”.

As far as I can ascertain, there is almost nothing in the academic literature on knismolagnia. However, there are a number of online articles and writings about the sexual side of tickling although there is a common mistake I have spotted which may both have arisen from a single source. Many online sources – including the Acarophilia and Kinky Sex Questions websites – appear to include tickling as part acarophilia (the deriving of sexual arousal and pleasure from scratching or being scratched) when in fact it is not (although there is clearly a fine line between hard tickling and scratching).

In 2006, Dr. Lisa Shaffer and Dr. Julie Penn developed a comprehensive paraphilia classification system and published it as a book chapter in Dr. William Hickey’s book Sex Crimes and Paraphilia. In this chapter, Shaffer and Penn made specific reference to both acarophilia and knismolagnia although these mentions (while in an academic context) were part of a wider theoretical point noting that some paraphilias (specifically acarophilia and knismolagnia – although they used the term ‘titillagnia’ for the latter) were completely “innocuous” and that this demonstrated that not all sexual paraphiliacs were sex offenders (and vice-versa). This appears to be supported by the Right Diagnosis website which claims that treatment for knismolagnia is generally not sought and that individuals with the condition “simply learn to accept their fetish and manage to achieve gratification in an appropriate manner”.

According to a small article on the Kinky Sex Questions website (which also wrongly interchanges acarophilia and knismolagnia), sexual tickling is most “frequently done by fingers, feather and other objects or by licking”. It claims that initially, the person being tickled enjoys and encourages the tickler, but then turns into “helpless laughter”. The article also claims that the preferred tickling areas are “feet, armpits, navel, ribs, breasts and genitals” (although no evidence is given to support the claim). If this is true there is likely to be some crossover with other sexual paraphilias and fetishes including podophilia (i.e., foot fetishes) and maschalagnia (i.e., armpit fetishism).

The Acarophile website also contains an “Acarophilia Dictionary” which appears to relate acarophilia to a more specialized and idiosyncratic sub-type of sexual sadism and sexual masochism (in fact there appear to dozens of websites that cater for ‘tickle torture’ pornography if you do a quick Google search). The website uses the word ‘ticklephile’ to define “anyone, including adults and children of both sexes who have an acute interest, or fetish, about tickling or being tickled”. It also features some more specialized definitions including the ‘Tickle Top’, the ‘Tickle Bottom’, ‘Tickle Torture’ and a ‘Douhini’. These are the verbatim definitions from the Acarophilia Dictionary rather than my own re-wording:

• Tickle Top: 
This refers to “the person who tickles, or tickle tortures another with the object of forcing the victim, usually restrained and helpless, to laugh hysterically, cry, scream, urinate, ejaculate and even pass out from prolonged intense tickling. Usually done with consent for erotic sexual gratification, but sometimes used as effective torture of prisoners”.
• Tickle Bottom: 
This refers to “the victim, usually restrained, of tickle torture, either with consent by a tickle top for exercise or sexual gratification or by others as torture to obtain information or for sadistic pleasure. If very ticklish, the ‘bottom’ suffers acute agony from the body’s automatic reflexes, such as hysterical laughter, screaming, crying, muscle spasms, urination, ejaculation, and even convulsions and loss of consciousness. Common in BDSM, (bondage sado-masochism) practice, the tickle bottom should be in good physical health because severe tickling can cause strokes and seizures”.

• Tickle Torture: 
This refers to a tied-up victim “be it in a rack or with ropes or hand-cuffs, in a strategic method, and tickled mercilessly. Usually, words are written on the victim’s feet, and pictures are taken, both still and moving. Rarely does sex occur, although erections and urination may”.

• Douhini: 
This refers to a “tickle of the inside of an exposed armpit. The Douhini-er must then yell Douhini to further surprise the victim. Usually accompanied by a slight wave of the pointer finger. In other cases a Douhini can also be a jab to the armpit but that technique is usually frowned upon”.

According to most online sources, the main reason why sexual tickling is popular among those in the BDSM community is because the person is usually already restrained. The dominant partner may also blindfold their victim to enhance the sexual pain/pleasure. However, one online gay fetish site claims it is not popular. It asserted that “although some consider [knismolagnia] a BDSM activity, tickling is not fully recognised by the community and is relatively unknown in the mainstream. In dominance and submission scenarios, sexual partners may agree upon a safeword to signal that the tickling should stop”. According to a Wikipedia entry on tickling games, knismolagnia is derived from the term ‘knismesis’:

“Knismesis refers to the light, feather-like type of tickling. This type of tickling generally does not induce laughter and is often accompanied by an itching sensation. The knismesis phenomenon requires low levels of stimulation to sensitive parts of the body, and can be triggered by a light touch or by a light electrical current. Knismesis can also be triggered by crawling insects or parasites, prompting scratching or rubbing at the ticklish spot, thereby removing the pest”

Knismolagnia also includes ‘gargalesis’ which according to an article on knismolagnia in the (admittedly non-academic) ‘Him and Her Sex Blog’ refers to:

“…harder, laughter-inducing tickling, and involves the repeated application of high pressure to sensitive areas. This ‘heavy tickle’ is often associated with play and laughter. The gargalesis type of tickle works on humans and primates, and possibly on other species. Because the nerves involved in transmitting ‘light’ touch and itch differ from those nerves that transmit ‘heavy’ touch, pressure and vibration, it is possible that the difference in sensations produced by the two types of tickle are due to the relative proportion of itch sensation versus touch sensation. While it is possible to trigger a knismesis response in oneself, it is usually impossible to produce gargalesthesia, the gargalesis tickle response, in oneself”

This short article also claims that varying forms and varying degrees of knismolagnia “from the pleasure experienced when tickled by a partner, to the sexual need to be tickled to reach orgasm”. It is also one of the few articles to note that knismolagnia doesn’t include non-tickling behaviours such as scratching and cutting. Of all the paraphilias I have examined in my blog, knismophilia appears to have been one of the least researched (academically or clinically).
