Hey I was wondering if masturbating had anything to do with burning urine. First, I am a 17 year old who has masturbated at least once a day for the past couple years. My urine sporadically burns and I have been tested for a uti and it came back negative. Is it possible that vigorous masturbation could have caused this and ripped some sort of tissue? Btw my urethra is red and meatus has red lips. Should I abstain from masturbation?? If you can help me, it would surely change my life.
