Hello, I stopped masturbation 2 weeks ago, since i stopped i get semen discharge maybe twice a week after urinating. The semen is thick and greenish color. I checked for all STDs except hpv because there is no test for detecting hpv, all result came back negative.. I have never experienced any kind of penile discharge in my life. This is the first time. Im 22 years old, male, single, don t drink alcohol, i only smoke .
