Hello, I am 16 and I just noticed that below the head of my penis, right where the skin meets the head, there are two holes. I am also circumsized. The holes kind of look like they have been caused by masturbation because they place where they are located is the part of the skin that gets pulled on. They seem like small pock marks and the skin just seems whiter inside of them. There is no puss or anything like that. I've never had sex before, just oral sex a few times. Should I be worried about this? Is it a serious skin condition? Or is it normal to have these?
