Ok bud, here are some thoughts on what you're dealing with. First, stop worrying so much, this type of thing happens to more guys than they are willing to talk about. Second, our two heads are very connected, so what you're thinking can really impact that lil guy between your legs. Problem is that once it happens to us it becomes really easy for it to happen again because we're so worried that it will. The cure is quite simple, but not always easy....it takes continued trying (oh damn, more risk that it'll happen) but usually things turn out just fine. Here are a couple of tips. You might try laying off the hand for a while and then put yourself in a position where you'll have a chance to use it, chances are your lil guy will be ready for action. Another involves simply not worrying about it and letting things just happen....enjoying the moment so to say. And finally, if your girl is a steady g/f and the two of you are close, just explain what is going on and ask her to help....I bet she'll be willing to keep working with you and things should be fine. I'd say start with her masturbating you and not go straight for intercourse, that way you're sure to have success and less chance for something happening. And heres one thing to remember, there is nothing wrong...you know your penis works because it does for you....so be cool and stop worrying! Hope this helps and remember....you aren't alone here....we've all been there and had this happen!
