I've noticed 3 or 4 quite small dark spots on my scrotum. No pain or bumps. At first I didn't think much of this, although I have recently been with a different partner. But once in the shower while masterbating, one of the spots began to bleed! Not alot but enough to notice, and has since not reoccured. Only other symptom I have had at about the same time is a jock itch & sticky feeling in my groin area. My dermatologist prescribed Protopic .1% for this, which has helped but this reoccures if I stop using the cream. What are the spots, and should I be tested for any STD?? Will the cream eventually stop the jock itch? Thanks.
