I have a clear tacky discharge from my penus, with slight discomfert in the genitalia, sometimes itchiness around the anus and sometimes slight discomfort around the penus. The symptoms started after a one night stand in december 2012. I was tested for all STD's, including bloodwork, urine, culture and semen culture and everything came back negative. Prostate was checked, ultrasound done and nothing peculiar has come up. My overseas doctor, recenly treated me for reactive arthritis, 3 weeks of Doxicillin with no effect. I have also taken cypro, Zithromax and Azithromicin, all to no effect.
