It's genuinely interesting to read what other guys don't like, especially when its things I assumed I wouldn't like either, but later found out how wrong I was. For example, fisting. Sex was always about sticking my cock in an ass or mouth, until a hot, 23yo, skinny twink asked my to slip my hand up in him. He got off so hard that I (almost always a top) had to try it. Having him make a fist in my ass & stretching me to max was insanely awesome. It was such a great experience, I eventually learned to fist myself & even fuck myself with my own cock & balls in my ass.
Same with water sports. Never even occurred to me to mix piss & sex until someone asked me to pee on him & inside him. Then I dated a girl who liked me to piss in her pussy & her mouth from time to time. Now I'm an addict for wet sex.
Some things I'm hypocritical about; like body hair. I am a hairy mother fucker, but I prefer my partners, male or female, absolutely hairless from the neck down. Especially their ass. I just think assholes & pussies are the prettiest things and I don't want anything blocking my view of them. I definitely want to see those pink parts up close in porn.
I noticed someone mentioned the new FTM trend. I think it's kinda hot in a way. However, the one thing I don't get is that it's nearly impossible to find FTM porn where they take anal. That doesn't make sense to me. If you identify as a man, remove your breasts, and take androgens, then why do you want to be fucked like a girl and not take it like a man?
