Edit: Oh yeah, one more thing. Plenty of guys want anal from girls but they get all offended when they think about doing it to guys. Plz. An ass is an ass.
For some people, there is more to sex than the physical movements involved. It's the same with kissing a different gender. I don't kiss guys. They have a mouth, so do girls... but I don't do that. Why? 'cause I don't like guys.
