Its embarrasing and is a se..

i have an even distribution of redness around my foreskin which seems like a rash; light redish color. when i am erect, it feels kind of course, as if it is dry skin. could excessive masturbation be the culprit? what can i put on it for it to go away? do i have to be worried about a potential disease?

Does it burn? Does it cause pain? Does it erupt, like come and go at odd times? Those are the signs your body is telling you about a problem.

If it is no to any of these questions, then if you are having a normal erection, doing and enjoying your masterbation, then continue.

Masterbation is actually good for your sex life. I would not be concerned about the excessiveness of this act. Just enjoy.

i think you have blemishes. im guessing you're a teenager, very common. you're probably trying to say that the "rash" looks redder when you're doing your thing -- it's because blood is rushing all over your body, therefore it looks "redder" and no, masturbation is not the culprit.

solution: take showers daily (if not twice a day), buy those over the counter kit -- cleanser, toner, and medication in one box, and use them. they're usually effective.
