In the past few months ive been having trouble with erections and seen 2 doctors. Both say im normal etc, it's in my head. I am 20 btw. Erections are just not the same. I am one of the most sexually confident people i know and I don't think it is mental. I have noticed a strange sensation during sex in the past month and realized that on the right side of my penis I juts don't have the sensation I am used to. I have like no response to fine touch. Compared to my left, top , and bottom which i do. It is actually a fairly large area. What happened, what couldve caused this? Is this permanent or is there anything I can do about it?
