I am 19 years old guy, when I lost my virginity at 18 and a year after that I could have sex for 1 to 2 hours and my partner having orgasms with no problems, my girlfriend even started to get worried that she doesn't please me or something. But now this past few month I have a little problem, every time we have sex I finish early, maybe in 15 to 30 minutes but this is a parablem, I always finish just before her, like just a little bit more and she would get an orgasm, just a few more strokes. It happens every time we have sex and it drives me and drives my girlfriend crazy. Can you please please help me and tell me what the hell should I do?

Relax the more you think about it the bigger your problem will get try more foreplay get her closer before you even get started then she will have a shorter distance that will match up with you climax

Well, you shouldn't really worry about it too much, if you guys have sex and you both get off some what one after another, or sometimes at the same time. It's a good thing. Just pay attention to her twitches, sighs and etc.. You'll get better with practice. (not saying you should go out and whore about, Everyone's diffrent) you'll learn that quickly. Just make sure you don't get her pregnant, that's the last thing you want to happen, seeing as your only 19.
