So, I went swimming at a beach in Florida. I was in the water for maybe an hour when my penis started burning intensely. I went home and took a shower and washed it and everything but it was still very sore. I looked at it the next day, and at the very bottom of the tip there was swelling, it looked kind of scar-like. The pain eventually went away, but the scar looking part on the tip is still there. It has been a year.... I don't know what is wrong with it, and I'm kind of worried. Any idea of how to make it go away? Or any idea on how to help it?
