<s>[INST] Hi doctor, I am a 21 year old male. Sometimes, after masturbation I feel urge to urinate regularly after every minute even though there is very less urine. Also I feel pain, some pricking and irritation feel while urinating. Sometimes, even without masturbation same problem occurs. Please advise me to get rid of this problem. [/INST] Hi.
