I don't know if this answers your question OP. I have a really bad foot fetish, (and I'm into socks as well). and everything about mens feet, tops, bottoms, soles, toes, even if a guy (and usually men do) has pretty rough looking feet, with corns, and callouses and ridges etc. I don't care, I like feet lol.
But unlike with Straight men and women. women show their feet quite often, and women like men who like their feet, and yeah. Women wouldn't mind sending guys pictures of her feet, and women wear high heels because men find heels on women attractive etc.
On the flip side being a man attracted to men/Gay and into mens feet, it's an easier said than done fetish, because most men do not like anyone messing with their feet, or having anyone look at their feet (regardless of the fact there are guys out there who don't mind raggedy mens feet lol). Guys are rarely seen barefoot/you rarely see their feet. Straight men rarely allow women to mess or see their feet, so you would think, it's almost impossible/they are hardly ever going to please another man/gay man into feet. You're not gonna find a guy who's down for that, or a guy willing to send you pictures of his feet, or let you worship his feet. So it's really hard to find guys who don't mind another gay admiring their feet so yeah.
One my my biggest fantasies is like smelling the socks and feet of like a construction worker once his shift is over, or like smelling the socks and feet of a business man who was working all day. I just know this fantasy is just a dream at this point. But I see a lot of "foot porn" and I'm not gonna lie, I like to watch it, because it's a fetish of mine, and I can't help that.
So yeah.
