HI DOCTOR I AM IN MY EARLY 50'S AND I WAS CIRCUMSISED AT BIRTH. RECENTLY I NOTICED WHAT SEEMS TO BE A SOMEWHAT BULGING VEIN IN THE FORSKIN OF MY PENIS, IT RUNS AROUND THE PART OF THE SKIN THAT WAS LEFT AFTER BEING CIRCUMSISED. tHE VEIN SEEMS TO GET LARGER AND MORE RIDGIT WHEN THE PENIS ERECT. THE VEIN DOE'SNT GO ALL THE WAY AROUND THE PENIS IT IS ONLY ABOUT 2" IN LENGTH. IT'S NOT PAINFUL OR ANYTHING IT JUST FEEL STRANGE TO THE TOUCH. DO YOU HAVE ANY IDEA WHAT THIS MIGHT BE?
