Why do I get the urge to pee, but end up not discharging urine?

You could have a urinary tract infection. It’s accompanied by strong frequent urges to urinate as well as pain while urinating. The reason nothing comes out is because the urge is so frequent the bladder has no time to accumulate enough urine.

You need to go to a doctor to be sure. If it is a UTI, you’ll be given antibiotics. It’s important you take the full course. In addition, drinking cranberry juice can help with the pain.

Go see your doctor. UTIs are common for woman.

I agree with other posters who suggest the possibility of a UTI, however another possible cause is just adolescent horn!ness.
5exual arousal, particularly if you have not been previously accustomed to the condition, may produce sensations which resemble the urge you describe.

Yup, sounds like a UTI- get a doctor to do a urine C & S and take the full course of ABX that he prescribes, do a follow up C & S 2 weeks after you finish the ABX to make sure that the infection is cured.
