I like the theory that the reason people like feet is because the area of the brain that controls your feet is close to the area that makes you feel things and in some people the "wires" can cross:
I think I just have a woman fetish. I've had "oh damn" moments with various body parts on different women over the years. Feet, hands, decolletage, ears, eyebrows... all sorts.
Kids. Thank god I'm not attracted to kids. Or animals. Anything else is fair game. Feet attached to a consenting adult are fine. Don't see the big deal. I like to spit-shine the rusty sheriff's badge, so why the fuck would I care if someone likes a boring regular appendage like a foot? 🤷
Unless there's some angle to this non-foot people don't understand? Like, maybe being turned on by feet is comorbid with an uncontrollable need to blast rope over any uncovered foot you see? Now that would suck.
I became interested in why foot fetishes occur recently.
Basically, it's the same reason why breasts are considered sexual (they aren't); it's all about novelty. If we lived in a nudist colony, neither feet, nor breasts would be considered sexy.
Feet get covered by shoes, making them more novel.
Tribal cultures dont regarded breasts, or feet, as sexy.
Though it begs the question: if nudity became normalized, then what would be novel?
People would find personalities, voices, power dynamics, and fantasies more or less erotic than they are now (for most people).
I can only touch it for like 1 second and quickly retreat. It's tempting to touch it for longer, but it's risky (I can get PAW'ed; aka: she swings the paws at me)
"I'm not attracted to feet, which is a relief, because to be attracted to feet is immoral" -- presumably the opinion of social conservatives regarding homosexuals instead of feet.
