Circumcisum scar

Patient: Im a 30 year old male. My entire life i have wondered about scar tissue that runs vertically down my penis. The scar runs just below the head of my penis all the way to my testicials. It is so prominate that there is a lip of unremoved skin along it, also stiching scars amd it is nearly s shaped. My family states there was no major proceedures other than circumcisum. What is it? Was the circumcisum performed wrong.
