Hello, I noticed that skin on my penis is getting darker and the skin is shiny, I also can t retract skin since I was 15 and I didn t had problems with that while having sex with my fiancee. I m 25 now and have this problem, can you tell me what to do, I m really worried. Thanks in advance. P.S. I also have darker and rougher skin patch on my elbow and above leg ankles, it appeared 1 year ago.
