Hmmm... If I'm going to fuck some guy, I prefer one who is really into GETTING fucked. They might have some 'fem' qualities (not totally sure what that means) but if they are man-enuf to take it up the ass and they don't just lie there, then I'm totally into it!
Since I'm not bi, I prefer to have sex with men because of how 'hard' we are, how we smell, etc. As long as my fuckbuddy/partner is hygienic (without being sterile), staying in reasonable shape, and is participating in the play (no starfish fucks, thank you very much), I'm happy to play too.
Oh yeah...Though I LOVE a noisy sex partner, I DON'T like one that sounds like a girl. Bring on the grunts and groans and moans. Just leave the high pitched sighs for someone else (remember: I'm gay NOT bi).
