A friend had surgery and is home recovering for a couple months. He has a specific sock fetish. As a favor, I sent him photos in the kind of socks and in a pose that excite him. Also, a guy at the gym asked if he could photograph my bare feet. I let him. Am I now a sex worker (though I didn't get paid?) What are your personal boundaries regarding kinks that you don't share but don't make you feel violated?
