Dear Dr Sexville*,
What is up with foot fetishes? How did that become a thing?
When I was 15, I dated a boy who had a foot fetish. Except that I didn't actually 'date' him, I pashed him a few times at the pub (where I shouldn't have been, because I was underage, so let's just say I was 18.) Oh, and except that he didn't call it a foot fetish, because he was only 16 (or 18, if we're still at the pub); he called it a 'foot fallacy'. Clearly, he was either not very well read, or he was prone to constructing elaborate, invalid arguments in which feet played a key role in the flawed logic. But I digress...
The point is, he liked to play with my feet when we kissed. Which means that foot fetishes have been around since at least my teens, which was approximately 70 billion years ago.
Fetishes occur when a persona becomes sexually aroused by any thing or body part that is not specifically genital, like feet, earlobes, bunny costumes, or a really clean living room floor. And fetishes are very common, even if the object of the fetish is not. There are fetishes for elbows, morbid obesity, the Eiffel Tower, even harpsichords. All of the men I've dated have all had fetishes, for objects as diverse as Lamborghinis, Porsches, Ferraris, and Honda motorbikes.
Foot fetishes, or podophilia, are the most common type of fetish, and they can be excellent fun. I slept with a man once who liked sucking my toes, using 'once' in the sense of 'many, many times' and 'toes' in the sense of 'yes, I mean toes' and it was thoroughly enjoyable.
The only thing to remember about foot fetishes is that, like other objects to be sexually enjoyed, they are best experienced clean. So if there's a chance your partner will be want to get dirty with your feet, perhaps a little wash with some nice peppermint foot scrub followed by a pumice and some soothing cocoa butter moisturizer wouldn't go astray. Unless your partner is a purist, and likes that straight-out-of-the-shoe smell, in which case rip off those socks and get into it.
And remember, a foot fallacy is something completely different. But we can talk about that another time.
