My penis head is one color but there is a rather noticeable lighter discolored spot. its almost as if it has lost its pigment and I don't know how. I have been tested for all diseases and the spot doesn't itch or feel discomfort or anything of that nature so i am sure it isn't a disease of some sort, but the area that is discolored also feels noticeably more rough that the regular skin. I went to the doctor and they told me this was normal but I'm not sure too many people have this. What are your thoughts & has anyone else experienced this?
