I'm 19 years old and i've noticed with my girlfriend the past few months that on the odd occasion I couldn't maintain an erection or would just lose the feeling of orgasm. Now I thought this was fine, but this past week I haven't been able to maintain an erection no matter how much I want to, and my girlfriend is really getting to the end of her ropes. I went to my doctor yesterday but he said that the equipment seems to be fine. But i've been feeling symptoms of stomach pain, the occasional testicle pain, and dulled sensation on the penis. When I masturbate I can reach orgasm, but last night when I did it was harder than it ever has been before. I also have a neurological disorder called charcot-marie tooth. My doctor said he will talk to someone about that and see if he thinks that is tied in with it, but other then that he might do some hormone tests. He feels that its probably something psychological, or external like the disorder or testicle pain.

This is tearing me up inside, is there anything you can suggest that might help?
