Tomorrow, or in a few days anyways, I am expecting to have sex for "real", what I mean is go all the way. (this is with a guy). I'm about 8 inches, he is 9. Now I have never had sex anally, so I am wondering, should I tell him that, or should it not be an issue if I am relaxed? We dont really know each other that well at all, but we want to play around. He is extremley hot, so I do want to, but I was just wondering about that.
