I've never given it a try. Or, I've given it a try and didn't like it. Or, I've given it a try and it was pretty fun. At some point I'm in the position of having to tell somebody to go away, I'm not having sex with you, and then there I am being completely ignored as whoever it is starts asking the same questions and running the same lines on the guy next to me. I've done that myself, of course.
All men have.
So I'm only relevant as an orifice, gosh thanks. This is where sluts come from. I had a friend like that when I was in college. She fucked a lot. And I loved her, I did.
