I am 13 year old male and I just started masterbating a few weeks ago I never checked my penis before I started masterbating and now I seem to find a large white spot under my penis I am hoping its a birth mark and I also have little white spots at the edge of the spot. I asked my mom if this is from I was a baby and she said yes. I need help and I started masterbating after my first couple of pubbes. Please help.
Well, if it's a birth mark, and your mother says so, there's nothing to worry about. Spots on the penis are very common and most do not have a serious cause. Papules are small (less than 1cm diameter) lumps, raised above the skin surface. These little spots do not usually have a serious cause, but some are infectious.
