My girlfriend and I have been dating for 6 months now and about a month ago we decided we were ready in the relationship for sex. Well, when we engage in foreplay we both get very aroused, but when we get to the point of it turning into sex, I become nervous and while she stays ready, for lack of a better term, I lose my buzz. I know this is probably nerves, but it has happened a few times now, and she's becoming very frustrated in the relationship and I'm becoming very embarrassed about my performance. Are there things out there that would help me keep my erection or maybe increase my sensitivity down there so that I can stay hard even though I become nervous? Hopefully if I can just get over the hump once, I'll be fine from there on out.
