I had oral sex with prostitute then after 2 months suddenly i had thick discharge from my penis.went to see doctor checked for urine test there is no infection found.today also i had discharge worried.mostly during blow time.

Urethritis?: Did you a similar question yesterday? (About discharge that appeared while at toilet, perhaps after a bowel movement?) This may not be abnormal, just prostate fluid or semen expressed during defecation. If not associated with bowel movement and if discharge continues, see your doctor at a time when discharge is present. Or sex is low risk, but can result in gonorrhea or nongonococcal urethrits.
