Please answer if you can! All of my past sexual activites involved in protected vaginal and unprotected oral sex. However, two months after my last sexual exposure....I saw this damn white patches of skin peeling off below the head of my penis. Looks almost like there is a cut. Specially it burns when I try to masturbate. I washed it with water and it burned. Then I applied some home based cream on it and skin was looking normal again. What it could be? Does it sound like any STD at all?
