I am 21, i have been sexually active since late into 17, and have been masterbationg since 16, but really compusively since i was around 18-19. Suddenly i have lost a lot of size, i went on a long time thinking that i was homosexual because my mind was not interested in it at all and i got really screwed up endochronicalligacly. I am now losing about half the size, it is not as hard, i am going to an urologist on monday but I am wondering if this size loss could possibly be permanent. last night i had sex with my girlfriend and was not really interested, about three inches decreased, maybe 3-4 inches, and lasted about 30 seconds. I considered myself good a while ago, but i masterbate about 3-4 tiems a day on a bad week. I am very nervous. i have gone as high as five, but I need help... any ideas?
