Patient: What would be the cause of pink, recurring, slightly shiny, occasionally flaking spots on the penis head and penis shaft? Not more than 1 or 2 round spots about 2mm in diameter at a time. Slight burning after urination or ejaculation, but nothing painful or debilitating. I could just be worrying myself into thinking it burns. They seem to heal and fade very very slowly, and seem to randomly pop up in different places on the penis. No discharge, nothing on testicles or anywhere else.
