I didn't used to like this but after playing a character with a foot fixation, I'm more open to the aesthetically pleasing aspects of this erogenous zone. I love the arch of a beautiful foot, the splayed toes and I'm sorta all over the curves from top of the foot and shin to the calves. I get really excited over the old pinup pics for that reason.
Lookit them gams! Vah-vah-voom!
Freud once said that foot fetishists are sexually stimulated and attracted to images of feet because they resemble penises. Charge me as guilty, then!
Some might argue that feet are not attractive because shoes are extremely damaging to our feet over time, resulting in micro malformations, thus our brains do not look at everyday feet as attractive but as deformed?
Simplest explanation for a lack of "majority" consensus on the attractiveness of feet is cultural. Just like the sexual attractiveness of breasts, which is not biological since in a lot of cultures all over the world they are no big whoop, or at least, not the crux of sexual appetite as they are in the Western World and the United States in particular. So, it is not unnatural to find feet sexually attractive, it's just a taboo because of the cultural impression of feet being gross or ugly in the modern Western world cultures. Why that exists? I'm still trying to find a source where it originates from. Victorian Era, maybe? You remember, those times when flashing an ankle was scandalous? Could be runoff guilt from that.
I do find it particularly strange that foot fetishists are so self-conscious and sensitive to their lack of acceptance... when such really doesn't exist, in my opinion. It's actually the most common non-genital, non-sexually stimulating body part to be fetishicized. Everything from feet themselves, calves, legs, and simply shoes and socks. You know who has it really bad? Guys who like to fuck armpits. The shame. I'd put foot fetishists and acceptance of their existence right up there with other unvanilla play, like rimming and fisting. You tell a gal you want to see how far you can fit your fist into her asshole in a non-antagonistic manner and you'll get about the same general reaction telling her you want to suck her toes.
