Hey guys.. I have asked this question on litterly hundreds of medical websites and havnt got a good answer...

I have a numb penis. I can feel a very small amount of pleasure with a flacid penis on the head... and can feel a larger, yet still small amount of pain in it. Its been numb for all my life... I know a lot of people asking this question had it for a couple of years.. but I have had it all my life. I started masterbating at around 14... I couldnt really feel much pleasure... but I still reached orgasm. Now im 16 its becoming a major problem. Back then, I could at least keep my erection... but now, I think I think about it it too much.. for the last two times i have masterbated, my erection went soft because of the stress of not feeling much... but I managed to harded it again slightly to reach orgasm, that wernt that intence. So heres my problems..

Numb penis
Low sexual desire.. hardly ever get horny
Lose erection a lot of the time
Getting slightly depressed from it

Im scared about my life in the future... Im scared that im gay (which makes me even more depressed) and its the fact im masterbating to the wrong things that causes my problems. I really do hope not though. I was horny the last time I masterbated.. then while masterbating for around 4 minutes my erection went soft... but I manged to get it again my rubbing the head and reached orgasm, that like I said wasnt that intence. My penis seems to be more sensitive when its flacid... for example when im in the shower and I put the water on the head of my penis while I pull the forskin back (Im not circumcised, so I just pull the forskin back in the shower to clean it) It feels great for about 5 seconds, then I urinate for some reason. Then it kind of goes numb, but if I leave it for a couple of minutes, I can do it again, but I would urinate less frequently and it would still feel good for around 5 seconds.

I really am hoping my problem is some sort of obstruction, (not the fact that I dont have any nerves or something) as that could be cured.... right? I know I need to go to the doctor... but what do I say to my parents... "It dont feel good when I wank.. can I go to the doctor??" as im only 16. Please help... its driving me insane and im terrified of the future.. I dont want a numb junk all my life :'(
