Excessive peeing, 15 times a day and pain while peeing for one week after having unprotected sex?

May be an infection: Urinary tract infections are rather common. It happens to people every day, all over the world. A man is much less likely than a woman to get a UTI. A person with possible UTI symptoms needs to see her doctor to get a urine test, and antibiotics if the test results suggest infection. Also, there are some less common medical disorders that cause UTI symptoms, but are not infections.
