Dear Sir, This happens very rarely like one in a month but happening for almost the last 10 years. Sometime after masterbation, I feel an urge to urinate. While urinating I get burning sensation. If I urinate it gets worse. By keeping myself in control and not urinating for about 30 45 mins, this burning sensation goes away. This doesn't happen daily. Mostly once or twice in a month, although I masterbate daily. What is it.
