When I make love with my girlfriend, I worry about losing my erection, and sometimes this worry seems to cause it to happen for real. This is very frustrating, because I don't want to worry about it, and when the thought enters my head, I get upset that it entered my head, and I get worried about the whole thing all over again. Then once I realize I'm doing this, I try to focus on the lovemaking, telling myself, "Just enjoy it, it feels good, and you're close to her, but of course in the back of my mind (and maybe the front too) I'm worried about losing my erection. And then it happens. This has been happening for years now, actually. It doesn't happen every time at all, but I worry about it enough that it has ended up sticking around. I don't want it to happen between my girlfriend and I, because she is very special to me. I love her very much, and I believe she is the person I want to marry (and I have never gone off "half-cocked" on that decision, so to speak . She and I talked about this this weekend, and I noticed that I was avoiding telling her that this has happened between me and other people I've been with as well, and so I just told her, and she felt much better -- she smiled and was very accepting, because she realized that it really isn't because of her, or that I'm not comfortable with her or something. We even joked around about it while we made love after that, because it really isn't a big deal; it's just nerves, and I know it will go away. But what I want to know is, do you have any tips? Please let me know.
