If you're the same 19 year old from Japan who asked a similar question, including pus dripping from penis, you can ignore my suspicion of STD .
But only if it is true you are a virgin, including no oral sex. At your age, UTI or urethral discharge suggests infection due to an anatomic abnormality of the urinary tract, such as restricted urine passage or stone. See a urologist ASAP.
