passing urine frequently is a symptom of urinary tract infection ( not necessarily fever would be there, can happen in some cases). This has nothing to do with masturbation. U need to consult an urologist/nephrologist,medicine spacialist and need to do a simple urine test. Absolutely no reason to regret about masturbation.

Yes, it is absolutely normal and there is no harm if you pass urine following masturbation. And the anatomical detailed explanation given by the dr Jitendra is very right. But what I understand from the question of the patient is that he is worried for passing urine every minute, if such is the scenario of the patient, then urinary tract infection is a possibility, primarily or secondarily. If i have misunderstood the question, may be.

Hello. welcome to healthcaremagic. In males, the urethral opening serves as the outlet for both urine and sperms. Under normal circumstances, due to the pressure created during micturition, the sperms are not allowed entry into the urethra during urination. Similarly, during sexual excitement, the urethra serves as the passage for sperms and not the urine. There are no valves and at times, some amount of intermingling may be possible. Due to the push and pull during sexual intercourse or masturbation, the urinary bladder may feel the extra pressure and hence the feeling of urination. This is absolutely normal and there is no harm if you pass urine following masturbation. Wish you good health.
