To tell you the truth, I really wouldn't know know. What have you seen while witnessing men having sex with boys?
LOL, I have to laugh at that. I was walking right into it! (oops....again, no pun and no association, please!)
I was just postulating; I can't imagine homos would always be satisfied w/just entry. I'm sure they would like to play w/some1 else's, not just theirs!
