Hi, I m 16 years old. For about 4 years now I have had a slightly red, slightly rising, ring like thing on the edge of the head of my penis. This has never been itchy and has never been painful. It makes it slightly harder to retract my foreskin over the head, but not too much. At first, I thought this was balanitis, but now I m not too sure. I asked my doctor about it at my last physical and he seemed to think there was nothing wrong, but I know for myself that there is definitely something unnatural and wrong. What do you think this condition could be? I could really use some help.
