hi i drink a lots of water daily .sometimes when i urinate i feel pain on my ( pennis). i have this problem from the time when i started masturbating when i was 14. but i havent paid much attention to this because quite rarely i feel pain on pennis during urinating. i m also sexually fine & like a normal sexual life. i feel like my semen comes out at times during urinating but i cant say surely because the pain only last for a minute only when i urinate ( only few times). can anyone of u tell me what my problem is & is there is any thing to worry in near future?
