I'm 16yr old guy, I have a UTI if I just sort of rub my penis maybe even pre-cum a bit but don't ejaculate, is permanent damage still a possibility?

Male Uti symptoms. Symptoms of UTI can be very variable and often may not be conclusively diagnosed without urine tests (urine analysis and culture). Pain/ burning sensation while passing urine can be due to inflammation of the urethra (urinary pipe inside the penis), bladder or even the prostate. True UTI in young male is uncommon and should be evaluated by a doctor with urine tests and In person physical exam. .
