Oh man I am having the same problems, EXACTLY. The cut is right beneath my head, and right above the line of circumcision. Its really irritating and I can't get rid of it. I have had it now for about 3 years. On and off. It heals, then gets worse. Right now it looks like its healing again, but never the less, I am sure that once I masturbate or have intercourse the skin will tear open again. If you could please give me some sort of advice, or let me know if it has gone away for you that would be great.
Thanks
The best way to get any skin to heal is to leave it alone for a while. I would use nothing more that vaseline and otherwise leave the skin and any scabs alone for a while, maybe a week. Penile skin doesn't just keep on ripping (unless it's traumatized), so you don't need to worry that this is some kind of chronic condition.
Best.
