Since past few months, I have been facing short pain in tip of penis. It shoots up all of sudden sometimes mild, sometimes sharp and goes of after few minutes. I usually urinate after sometime and it doesn't repeat. Used to happen sometimes like once a week, but these days more frequently. And also if i drink water, then I tend to urinate more frequently. I can stay without water full day then no issues. But if i drink tea, or have something liquid or drink glass of water urine starts shortly sometimes in interval of 30 to 20 mins. I never had sex. But used to masturbate a lot. Please advice.
