It burns when I pee. Mainly if my pee when my bladder is pretty empty. So drink water mostly helps, but not all the time. Sex  I feel like I'm dealing with this problem on a daily basis. I don't need to pee often and I went to the urologist and she said there was no infection.  I know sex doesn't help.All my symptoms started when I became sexually active.  When i was stopped having sex for a month the symptoms went away. I have no idea what could be causeing this, anyideas?
