Yes I am circumcised. I've only noticed it for a month but it's possible it may have been there longer. Like I said, you have to really look to notice it. I keep an eye on it every day and it hasn't gotten worse. But it's still there so it bothers me mentally.
Doctors see many patients, you see only you, I assume. You're far more likely to be aware of change / a trend, and changes can be a good clue or symptom..
While this sounds innocuous I suggest if readily able, that you keep a photographic record of the area of concern, to see later if there is a continuing trend or change, and to have something you could show your doctor later.
Are you circumsized or uncircumsized?
