a couple of weeks ago my foreskin first went dry and cracked, shortly i had pimps on the head. They eventually wen away after fours.During that period i was using antibiotic cream, which i stil use. Now on the frenulum, it is white and torn and looks sallowen. This has happened to be when i was a teenager.Alone the corona, there are small pimps which are less than 1mm in size. What could be this?
