I have the same problem man. Not that extreme but along the same lines. I can get it up after a lil bit but it will variate in size throughout sex. I know how frustrating it is.

Can anyone help me ?

Hi alex. Try not to be scared...I really think you're fine physically. Just one unpleasant experience can easily get stuck in your mind, so you were probably (maybe even subconsciously) worried that since it happened once, it would happen again. I know this is easier said than done, especially since i'm not a man so I don't really know how you feel, but try to forget the first couple of times and just relax. Don't go into it wondering if it will happen again. Try to completely put it out of your mind. If she's willing to try oral on you, that could help, too. I know I can't exactly relate to your problem, but women can have similar problems--for example, difficulty reaching orgasm--and once you're afraid something will happen, it will keep happening until you stop thinking about it. I hope this helps.

Thanks tasha, that helped a lot. Any other advice any1 can give me ? Anything I can change in my diet or something that will at least help ya know

It's nerves; it doesn't matter if it's with the same girl or not; it's nerves. (yes I know I said that twice.) just try to prolong it as long as possible with things like "romantic talk" and foreplay.

Think of what turns you on and you kissing that before you take off anything... Lol... Just an idea...
