The birds’ and the bees’ knees: A very brief look at genuphilia

One Saturday night while my family was watching Strictly Come Dancing, I found myself idly Googling looking for inspiration for a new blog. One of the pages I found myself on was Kinkopedia’s ‘Kink of the Week’ website. This particular page made reference to ten “paraphilias you may never heard of”. The list (in alphabetical order and the website’s definition) included bromidrophilia (sexual attraction to body odours and smells), genuphilia (sexual attraction to knees), mechanophilia (sexual attraction to cars),
 mythophilia (sexual attraction to myths, stories, or gossip), nasophilia (sexual attraction to noses), onomatophilia (sexual attraction to words, or a certain word),
 rupophilia (sexual attraction to dirt), sitophilia (sexual attraction to food), spectrophilia (sexual attraction to ghosts) and 
vorarephilia (sexual attraction to eating or be eaten by another).

Regular readers of my blog won’t be surprised to know that I was aware of almost all the paraphilias on the list (in fact I’ve written blogs on most of these). However, the one that jumped out at me (no pun intended) was genuphilia. Given the fact that (i) there is absolutely no scientific research on genuphilia, and (ii) genuphilia does not make an appearance in either Dr. Brenda Love’s Encyclopedia of Unusual Sex Practices or Dr. Anil Aggrawal’s Forensic and Medico-legal Aspects of Sexual Crimes and Unusual Sexual Practices suggests one of two things – either that this particular paraphilia does not really exist, or that it is a relatively newly realized fetish. It’s also another paraphilia where the name appears to have been derived as the opposite of a known phobia (i.e., genuphobia – an irrational fear of knees).

In researching this article, I have to admit that I almost gave up on trying to put a blog together given the lack of material (academic and anecdotal). I read an online article about sexual paraphilias in the new (fifth edition) of the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders that referred to genuphilia being related to gender but then quickly realized the article was a funny April Fool’s Day spoof (still worth a read though! See ‘Further reading’ below for a link to the article). Over at the Psyche Time-Lapse website, genuphilia made an appearance in their regular ‘Word Of The Day’ column. The writer of the short article noted:

“Getting on your knees is usually a prelude to some sexy fellatio initiation or submissive roleplay. But sexiness isn’t always just coded into the act of falling to your knees; it can be on the knees themselves Genuphilia refers to a special, sexual attraction for knees: knock-kneed, knobby knees, replaced knees, any one of the jumbly joints that allows our legs to move efficiently and helps support body weight. The area right behind the knee can be a sensitive, often-ignored erogenous zone, and light, tantalizing strokes on and around them with your fingers can bring shivers to a partner’s body. And with fall approaching, showing off your knees with a variety of knee socks, boots, and fall-length coats has never been easier!”

As a last resort I went online searching on various forums and discussion groups and only located a handful of self-admitted accounts of people claiming to have a knee fetish:

Extract 1: “I think I must have had something like this for as long as I can remember. When I was aged 12 [years old] I was nearly always in shorts and there was a near neighbour who was a girl of about the same age who had a mix of boys and girls as friends and she liked us to show our legs as she thought it was cute that boys were in shorts and that we boys showed more leg than the girls. As I got older I always thought that boys in school shorts looked cute and was jealous that their uniforms allowed shorts while the school I was at would not allow shorts. I was attracted to my ex-boyfriend when I moved to another school and saw a guy in shorts which showed off his long sexy smooth legs. As he and I saw each other out of school, he encouraged me to shave my legs so that we could rub our bare legs together. I noticed in particular his knees were turning me on and we took it in turns to feel each other’s legs and I concentrated on rubbing his knees with mine. I love to show off my knees as much as possible and when I see both guys and girls showing theirs, I feel very aroused. There is nothing so good as a pair of sexy knees”

Extract 2: I got a foot fetish and a leg/knee fetish, but I also got a fetish for a girl’s hands too. Anybody find that to be common out there?”

Extract 3: Hairless Inside Knees on gay men are amazing! That we are agreed that is why you are here at the internet’s premier Hairless Inside Knee Gay Fetish Website! Don’t get us wrong we love hairy legs on our gay men. But there is something about the inside of the knee that when it’s hairless sends our pulses racing. Here at THIKFG you’ll find sexual tips to satisfy your hairless inside knee gay partner as well as fantasies and the best photos and videos of the best hairless inside knees around. So sit back and enjoy!”

Extract 4: “I haven’t explained what my happy page is about yet. Knee Fetishes!…I know you guys are thinking. THIS IS WEIRD! But [you] know what? It is weird. It’s the next big thing. Haven’t you heard? Pretty soon everyone will be having knee, elbow and ankle fetishes…So I would just like to take this moment to tell all you people, look around. There are many knees. Some are ugly, some are beautiful, some are hairy, some are lumpy, some are squishy. Just enjoy yourself. Stop and look at the knees”

Presuming these extracts are genuine (and I have no reason to suspect they’re not), a few tentative conclusions can be drawn (even from such a few extracts). Firstly, based on these accounts, knee fetishes (and genuphilia paraphilias) genuinely exist. (I would also argue that the existence of dedicated websites such as The Knee Pit Gallery also suggest there is an audience and niche market for sexualized knee enthusiasts). Secondly, it appears that both men and women may have this fetish/paraphilia. Thirdly, it appears that genuphilia may occur within different sexual orientations (i.e., heterosexual and homosexual). Fourthly, it appears that genuphilia may overlap with other more established sexual paraphilias (such as hand, leg and foot fetishes [podophilia]). Finally, it would appear that childhood experiences may be critical in explaining the etiology of gunuphilia. The most detailed extract appears to suggest that the sexual liking for knees may be explained by conditioning processes (i.e., classical conditioning). I seriously doubt we’ll see academic research on genuphilia any time soon but that doesn’t mean it’s not a genuine sexual fetish/paraphilia.

  1. I can honestly say that I have a knee fetish, and it is real and very powerful. I want to suggest that knee fetishes are not much mentioned or researched, not because they are obscure and weird, but rather because they are not, and so my be taken for granted. When the weather warms up a bit in the spring, you can observe that more and more people gradually start wearing shorts and short skirts that emphasise their knees, something that obviously pleases me no end. I have to wonder wehther the knee fetish has in fact been absorbed into mainstream culture.

    I had never heard of a knee chakra until I looked it up in a search engine, and the first entry I came across did say that we have minor chakras around our knees. This may explain a lot. I don’t know enough of the theory to know whether such chakras can become more powerful if you pay more attention to them.

    Several acupuncture meridians are routed near to the knee or on the knee-pit too, which could perhaps explain why pleasure can spread all over the place from erotic activity in these areas.

    I know none of this would have any credibility in western science, and I’m only pointing to possibilities.

    I have occasionally come across others on the internet who talk about having knee fetishes, but not many. Sadly I have not yet met any of them away from the internet.

    I’d call this fetish gonyphilia, which makes both halves of the word Greek-derived, but now I’m also going to look up genuphilia, which I’ve never seen before. Genu is Latin, of course, as in genuflect.
