I never had problem getting it up with my girlfriend, but we broke up like 3 months ago (mutually, and still good friends). In any case, I was with this girl that I've been getting to know on Friday night and I could not get it up. We were both naked and I got her off. But I could not keep it up. The second time she went down on me I managed to stay hard for a little a while, and she was giving me the best head of my life. Deep throat and everything. And then in the middle of it I went soft. She was like and I was like So embarrassing and emasculating. Any ideas why this happened?
