Yes, I have the same problem like this man. If i don't masturbate for two days, when I go bathroom for doing #2, i can see the semen coming out of my penis. I'm sure, it's semen coz I feel it when it comes out. It smells same as semen and it comes out for few drops. There is no burning feeling, no pain, nothing else. I haven't had sex since it happened but if i masturbate i can't stay more than 2/3mins. I used to masturbate a lot in my early ages. The problem started to happen since i took a drug containing codeine phosphate. I'm really scared now. Should I immediately visit any urologist? Or any skin or sex doctors? Please let me know.
