man some of you guys are are so homophobic!
"if some guy ever tried to hit on me... I'm kicking him in the balls. " "Cause I didn't wanna beat the crap out of this guy!!" etc.
I hope that women don't get that kind of mind-set. But most of these men are treating you the way that men treat women in general. However, they feel they can (and probably can) be more direct since there aren't any of those weird woman-games involved. If you want head then say yes, if you don't say no, and it's probably the end of story. Unless it's some really creepy pushy guy in which case some ass-kicking may be in order.
Me, I never get more than a stray feel-up, even when at gay clubs (an awesome place to take women, by the way!). I don't groom nor dress myself well enough.
