<s>[INST] When I was masturbating there was a small amout of blood coming from the hole of my penis, this is the first time what caused that. i then tried to finish masturbation to see if it was the semen that consisted of the blood it did not (was clear semen). the little blood dried up within 30 seconds [/INST] Hello,I suggest you to avoid masturbation for couple of weeks till your urethra gets healed. If you experience any painful urination or blood in urine again or any purulent discharge I suggest you to consult your doctor to run some tests for infection and treatment if needed.Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Sameen Bin Naeem, General & Family Physician </s>
