What you need to do is post on the dermatology board, or men's health. This forum is for std information. Sexually Transmitted Disease. You are a virgin. No sex = No std. What you have going on is not even a symptom of any std known. We cannot help you on this board, so please try one of the other forums I mentioned.
i googled imaged the word and my condition looks nothing like psoriasis. i may have not explained it properly. my condition looks just like a patch of dry skin and its no where else on my body just on the middle top of my penis a few centimeters before the head. it is a bit discolored but not red, sorry about the misunderstanding. It's just in a lighter skin tone than the rest of my penis.
You do not have an std. You have not had sex, nor does a red dry patch signify any std. It sounds more like a skin condition like psoriasis.
