Yeah, I don't like doing this to a forum of people I don't know, but I figure you guys can probably offer some help.

So, here's my situation: I'm 18. Still a virgin, though likely not gonna be one for much longer. I've been going out with my girlfriend for about a month now, and we're close enough that we've been wanting to have sex with each other (she's not a virgin). Unfortunately, I've been having some difficulties with keeping my hard on when we get our clothes off and are ready to actually fuck. Usually the loss of erection happens in the minute or so space where I get out and put on my condom. Well, "usually" as in two out of the three times we've tried so far. She's been really amazingly understanding and cool about it, but even if she's fine, I'm certainly not feeling fine with it, and I don't want it to stay a problem.

I'm about 95% sure it's all in my mind, because I don't have a problem keeping it up when masturbating or when getting head, and I often get lingering erections when we're making out and such (again, I'm 18), but once we're naked it only takes seconds to lose it.

It's possible it could be physical, though, i don't know. We've always had lots (at least an hour or so) of foreplay, and it's possible that in that time the pre-cum and such results in something, because I generally only have a solid erection for the first twenty minutes or so and then it's more touch-and-go, but...I don't know, it certainly seems like it's a psychological thing. anyway, it's monday night now, she'll be staying over friday night, and I'd like to get through it and start really enjoying the sex asap. It's hard to just 'not think about it', because I'm already the type that thinks everything else to death, much less a problem like this that's making me struggle with my self-esteem and I don't want to have become a big thing.

So what do you guys think? Any suggestions or similar experiences?
