Ummmm... little problem! Help!?

I don't get what you mean about the concept of being a is gross rather than just being a is gross? It seems like the same thing to me. Or did you mean you have no problems with s, you just find the idea of sleeping with a girl yourself to be gross as you are straight. Cos if that is the case you should apologise to her, and explain what you meant. It would be best to talk to her before things go too far.
