I am a 40 year male. My urologist has recommended that I get circumcised because of smug a buildup which is causing irritation. Please advise?

Good advice. Will take care of problem once and for all. Giood luck.
Circumcision. I think it's not a bad recommendation. But if you are not happy or not satisfied with that, just let him know you don't want it. You could always get a second opinion.
