I have a very serious problem. I'll start from the beginning. About 10 months ago whenever I would ejaculate the tip of my penis around the urethra would sometimes go numb for a few minutes. I thought nothing of it and that it would go away. This went on for a few months. Then when I was masturbating my penis became completely numb with a sharp pain. I had to sleep with and ice pack down there to fall asleep. Also with the pain came a purple discoloration on the head of my penis that I am very concerned about. I initially thought I had damaged nerves. This pain has been miserable and I couldn't get in to see a urologist for a month. The urologist checked my prostate and when he touched it, the pain in the tip of my penis became a lot worse. He said the discoloration was normal - he barely looked at it. He was puzzled about my situation, but gave me antibiotics for an inflammed prostate. I knew this wouldn't really do anything but might make me feel better. I ended up going to another urologist a month later. He said he was 99% sure I had prosatitis and now I'm on my second month of antibiotics. He also said my discoloration was normal. I KNOW IT IS NOT NORMAL! Since then Iv'e had some good days, mostly bad. Even when I can get an erection that feels somewhat normal I am worried about the pain and discoloration. I believe that I do have prostatis but that it is caused by urethritis, even though I don't have wierd discharge coming out. I am almost certain this is from masturbation.
