Hi unfortunately I have been masturbate for 10 years and in last 5 years, when I felt like sperm is going to come out, I blocks it with my hand wrapping it around, so it stays inside and I can keep going. (it keeps going up to 2 or 3 hours). Its been 4 months that I always feel like I need to pee.(after last time I did masturbate like this) like always, 24,7 this is with me. I did ultrasound and urine culture, everything was fine specially my prostate. I decided to quit masturbating and I haven't done it for a month now. I went to the urologist 5 times and it was unsuccessful. Even for 1 month, I took one tablet of levofloxacin 500 every day, but still the problem was not solved. I have never drank alcohol or smoked. What's the problem? Should I be worried? How can I fix it?
