Why Do I have a "tight ring" around the middle of my penis?

I am a nurse and I have seen peope with your problem before. IT is more than ikey a stricture. That is a tightening of a circle of skin that seems to be cutting of some of the circulation. The urologist or plastic surgeon can help with that, its a simple procedure that involves relesing the tight band of skin from just underneath. Under anesthesia of course with a few days healing time and you should be back to normal. Definitey should see someone because it could become worse and cause all kinds of problems. Its a minor surgery and although anything "down there" is scary it really is just under the skin and heals very nicely.
