I'm going to give some background so if you don't want to read all of this next part you can skip down to the underlined word and after. About two and a half or so weeks ago I lost my virginity to my girlfriend... we're both 19 and she's had two BF's before. She has never had an orgasm during penetration (I can do it pretty easily with my fingers), so of course I want to give it to her. As of now, though, I have enough trouble lasting five minutes before I have my own orgasm, so that's something I could improve on, partially by getting used to the experience (we've done it five times since), and only one of those times was I completely erect. Needless to say, she could tell. So, it seems that I have a problem becoming completely erect before actual penetration (foreplay and so forth included) or once erect, I have a hard time staying hard once I'm in... even though there's no reason sensation-wise as to why I would be going soft. (I do, of course, use a condom.) So... To the good folks at LPSG: Do you have any advice or feedback on how I could fix this? Maybe different positions would help (her approach is to not try anything else before you get one right... so we've stuck to missionary, though she's flexible), or maybe there's something else I can do to improve my ability to become and stay erect?
