Hello, I am a 20 year old healthy male with no history of urology problems. Recently i have had a constant, mild burning / irritation in my urethra since i last masterbated. It's been about 4 days. I have been drinking a lot of water and staying very hydrated. I only masterbate about 1 time a week and this feeling has never persisted. the burning does not get worse when i urinate, so i do not think it is a UTI. Oh and it is not an STD... and yes I am sure. (i am shy) any suggestions?
