I am a 20 year old male who has had no hard erections or morning wood for the past year. I could barely have sex with the help of viagra during this period, but now viagra has no effect what so ever. Now i dont even have the ability to masturbate and rarely think about sex. prior to being age 20, I had what i believe a raging sex drive, I would connstantly think about sex and masturbated 3-5 times a day every day. I have seen many doctors and one urologists and they all say it is in my head, meaning psychological. I had blood tests, and they say everything is normal with my testosterone being in the normal to high range. This condition has ended many reltionships and without wellbutrin, I am near suicidal and suicide is constantly on my mine without wellbutrin. My question is what could cause this? is there any cure? or Im i stuck with this for life? I barely have enough motivation to make it through the day. please help and offer any advice.
