Thanks a lot, people. Fuck it though; Fuck it. I wanted to be able to use your advice and "get back on the horse", but it's not going to happen with my current girlfriend. There was a bit of a scene today...

We were joking about penises when she said "why don't I just strap one on?" I said "Okay." She gave me this sort of look I don't want to even think about. She asked me if I was gay over and over and over again, ands was immensely weirded out. She now thinks I'm gay because I like strap ons. Me and he are WORLDS apart sexually, and I don't think I'd want a girl as vanilla and close minded as her to tie me up anyway. I think I'd fall asleep.
Still, great advice. I'll put it to use should I ever break up with my girlfriend. I will never date another non domme girl again. Sex isn't everything, but why should I have to deal with this stuff?
