3 or 4 months ago the opening to my penis started tearing downward. I went to a doctor but he glanced at it and said it was fine. Since the. It has not healed, and if anything has torn farther down (it's a little over a cm now). I'm very worried as it does not seem to be healing at all. I tried not having sex or masturbating for 10 days and nothin healed. It gets soar and stings slightly after I masturbate but no real problems when I pee. I'm seeing a urologist soon but I'm hoping someone can help me with this now, as I've seen other questions on this site with the same problems but no answers. The tip is also constantly sore and red. I'm 18 years old and 195 lbs if it matters. I really need to fix this as it is unsightly and making everyday living more and more problatic and I fear it will only get worse. Thanks for the help
