I'm a 45 year old circumcised male. About 2 months ago, I noticed what I thought was a small, circular abrasion on the side of my penis, and also on the top of the shaft, just below the glans. I've had similar before from sex, and they usually go away in a couple of days. These have not. Now there are two spots about the size of a pencil eraser on each side of the shaft just below the glans, and a spot about the size of a dime on the top, with a little extension from the shaft onto the glans. The spots are not painful or itchy, are not raised, and are dry. Sometimes the skin flakes a little, and beneath is red and very shiny. The spot on top has spread just a tiny bit, and where its spread is noticably redder and shinier than the rest. I used lotion for a couple of weeks, which cured the flakiness, but not the discoloration. Also tried 1% hydrocortesone for a couple of days, and also Lotrimin anti fungal, nothing seems to help. I am sure this is not any kind of STD. Ideas?
