It's funny, I find cum facials really hot, but actually swallowing cum makes me gag!
Don't like most body piercings, or too many tattoos. A little ink can be hot, but too much just looks trashy to me.
When guys use fake porn dialogue during sex (on one site that has a forum the members had a contest to count how many times a particular model would say "oh, fuck" during his sex scenes!!! I think it got as high as 60+!). Reminds me of the OLD days when porn didn't have live sound and it was dubbed on later with ridiculous loops of fake moaning and stupid sex talk.
And don't judge me, but uncut cocks just creep me out! Turns me right off.
