I have missing skin on the top of my meatus or tip of the penis. It is red and irritated and has been like this now for 8 months. My meatus gets almost "stuck" together with a clear substance, and dries. There is no discharge. When I urinate no pain. It only hurts or causes some discomfort when my meatus rubs up against my underwear. I went to the uriologist and the doctor and both told me it appears to be irritated due to friction from my underwear. My skin gets better and starts to get back to my normal skin color but then when something rubs up against it like my underwear it gets red and irritated again. I recently got checked for everything possible and it all came back negative. Does anyone know what can be the cause of this? Fungus, disease, or underwear friction? I am so tired of this!
