question: I have 3-4 dry spots around my penis, but i never came in contact nor had sex, oral, etc. i usually wash with soap and water sometimes, but i stop washing it with soap and used just water. I masterbated since i was around 13-15 then stopped last week. I am 18 and i know it is not std or any diease possibly. So i still wash with water and the dry patches are still there. Should i be concerned?
