I also agree with Dan on avoiding dating bi men. I just don't want to date someone who may or may not have an interest in down there, because I don't want any guy to touch, look, or be aroused by it. For this reason, I don't want to date bi men. Do you realize how unfair it would be to say,"I know you like it, but you can't touch it"?
Straight men. Only. Though I'm sure there are exceptions.
I also, am reluctant to date a bi guy because I admit. I am scared he will cheat on me with a man. Which probably isn't fair. I'm much more open to a relationship with a bi woman, however.
