Hi. I've never spoken to anyone about this before but after so many years it's really getting me down and maybe was a the trigger for my depression. I'm 23, skinng build, but with a very deep voice and large penis. 9 inches by 6 1/2. The thing is I never become fully erect. Not on my own, not with a girl. Not once have I ever acheived intercourse when I'm laying on my back, I can't maintain. In the mornings I'm usually semi-hard, if at all. When I'm with a gf and very turned on I can just about maintain an ercetion capable of sex, but rarely and my gfs usually resort to oral to get me off. I haven't been to my doctors, assuming he'll say its all psychological, even though it's alwas been the same, and I'm super relaxed with my gf and she knows about my problem. I did try buying some pills of the intenet, viagra and cialsis, they looked genuine, bt had no effect. I was hoping anyone with experience would be able to shed some light on this. Does size affect the firmness, maybe I only have the blood for a regular sized penis? Please help, and thank you, Lee.
