There's nothing to be embarrassed about; it's just a skin rash that happens to be on your penis. You don't need to mention masturbation, which undoubtedly has nothing to do with it.

Have you ever heard of this before. I'm getting a feel like I am the only one with this is it rare or somthing??? what is dermatitis I'm not familiar with it?? I know I should see a doctor but im kinda embarassed about it at the same time. :\
Masturbation, however "excessively", will not cause skin abnormalities. "Cracks and dryness" might be normal or some sort of dermatitis, but in any case doesn't sound serious. But stop trying to guess, and do not expect a definite answer online. See a live health care provider; that's what they are there for. In the meantime, don't lose sleep over this.
