Im 16 years old. after urinating, i get the urge to urinate again after an hour or two. i don't drink too much fluids. how long after peeing should you get the urge to pee again?

Possible infection: You should be able to go longer between urinating unless you are drinking a lot of fluids,which you said you weren’t. There is no specific amount of time. There are several possible causes for your frequent urge to urinate.You might have a urinary tract infection, especially if there is pain;or possibly an irritation inside your penis. I would recommend being examined and have a urine sample test.
