Hey guys.. I'm 20, i don't smoke, rarely drink...all around pretty boring lifestyle... However, I have a wicked time getting an erection. I can only really if i'm having sex. If I'm masterbating, i pretty much have to play with it for like an hour, it gets hard, and a few seconds later i'll cum. If I do get hard, and I don't cum right away, i'm limp again... Anybody else have this kinda problem; or is it not even a problem?
