Penile Discharge. Some time it is Pus like discharge and sometimes water. I feel a little pain while urinating. Urine is yellow until I drink a lot of water. It even happened that I urinated a very little amount of blood due to not drinking water for a long time. I took Citralka for 5 days and I am not sure if it is worked or not. But now it past more than two weeks and the problem is getting bigger to me. I need immediate help. And moreover I need suggestion about this problem. Is it so serious problem? Is it a problem that can make me trouble in future. I am just 19 years old and never had sex (mentioning as it may be a case of std). Thanking You.
