On the foreskin at the HEAD area there is this area of skin that is beginning and getting darker as time goes. This started like 6 months ago a small weird black spot on my head “penis”. My penis (the head) is pink but this dime-sized scar is black so it is completely noticeable. It is right on the head. I don’t know what happen for some weird reason. I was worried it could be an STD?
I need your advise thanks!
