I had intercourse with my girlfriend 3 months ago. Immediately after sex, I felt a burning sensation in my penis like a bruise. I felt it would heal but the pain persists. I don t feel pains when I urinate or have intercourse. Pain only occurs when the tip of my penis touches my underwear. There are no visible scars on my penis and there is no external pain. Please how can i solve this internal bruise like pain?
