Hi, I have had a red irritation on the tip of my penis for about a month. I have treated it with vaseline and it always looks much better after a couple days, but it won't go away completely. When I first noticed it, it was a dry flaky patch of skin. Whenever I masturbate it gets redder, then I leave it alone for a few days looks like it's almost gone, but won't clear up completely. Sometimes I can see a couple tiny red bumps too. It's about a 1/4" patch of skin. The vaseline helps. I have had dermatitis pop up randomly on other parts of my body before. This has been around my eye, and on my chin under facial hair. Also I have not had any kind of sex in about 6 months.
