Over the past year, I have been getting pimples on my penis once a month about. They stopped for a while, but recently came back, and now I have about 3 or 4 small pimples on my penis. I am not sexually active, so I know it's no STD, but should I be worried? And is there anything I can do to make them go away? Also, should I see a doctor. I know it's bad but I have been rather hesitant, because it's kind of weird/embarrassing.
