I have a white spot underneath the head of my penis. After a dry humping session, a very minor skin irritation resulted. The skin irritation actually took quite awhile to heal. Though there was never any pain or other symptoms, a white spot resulted that continued to form small skin flakes--not really scabs, but more like a patch of dry skin every once in awhile. It has now remained for three months, though it has diminished in prominence greatly. The white spot is beneath the skin and unnoticeable when flacid. However, if I stretch the skin around it, its appearance becomes more prominent.
No STDs I can find on the web have similar symptoms. Help, please.
