Hello, for the past two years or so I have had spots on the shaft of my penis. Recently they have begun to appear on the glans as well. They are fairly small, not raised, dry, red, somewhat shiny, and flaking (at least on the shaft). They do not itch or hurt in any way. I have had an STD and HIV test, which was negative for everything tested, and had not had a sexual partner for 2 years prior to the appearance of the problem. I am now 24 years old.
