I have two brown spots on the head of my penis. I had it sence I was likttle and there is a little whit dot bump on it to, I also masterbate alot.

It . It is unlikely that the brown spots you are describing have anything to do with frequent masturbation. If they have been present since you were a child, the odds of it being something serious are very slim. The spots may represent common skin moles, or even skin follicles. If you are concerned i suggest you bring this matter to the attention of your doctor. Good luck.
