Not all, but some do. Some people think I'm weird because I think I have cute feet lol. Some people do and some people need to keep the socks on! my best friend always hates feet, she gets mad if you put your feet on her lol which I do sometimes just to make her squeal.
Yes, I can't watch people licking, touching, or massaging feet either. Mostly, it's because mine are SO sensitive, the touch of skin feels like fire, or sort of a tactile "nails on the blackboard" effect.
I'm not grossed out by ALL feet. Men's feet are usually pretty gross. My boyfriend's aren't the cutest, to be sure. But I like when he kisses mine and sucks on my toes and shit. Lol. I know it sounds weird but it feels good and he doesn't seem to mind it considering he's the one who started doing it on his own. He doesn't really have a foot fetish, though. I guess it's just another part of my body to him.
I've grown to love my feet even more after having been told how "beautiful" and "sexy" they and my toes are. Some of my guests have foot fetishes (I work at a cam site) and even more specific than that, some of my guests a giantess fetish and feet often play a big part in that. They're always complimenting my feet so they must be something special. Lol.
