hello , I have been looking all day on the net with no results , my boyfriend has developed a white patch of skin about 1cm , irregular in shape on the lower part of his penis , it is not sore or raised or itchy and he has no discomfort or discharge , could you give me an idea of what this could be , he recently had unprotected sex with another woman and I am afraid he may have caught something from her and in turn may pass or already has passed it on to me. Many thanks, S.
P.S I have looked up so much info on vitiligo and also lichen sclerosus and I am pretty certain neither of these apply .... any other ideas?
