I had protected vag sex with a woman of high chance of STD 8 wks ago. 10 days later, I saw a clear penile discharge and I went to the ER. They did a culture for gonorrhea and chlymidia and gave a single dose of cipro and zithromycin and 28 days combivir and viread for HIV exp. After the cipro and zithro, I still felt discharge. The chlym and gonorr tests were neg and I saw an internist. She gave me an HIV PCR test which was neg, noticed a fungal infection with the discharge. A urologist gave me 10 days of doxycycline and metronidazole and did another chlaym, gonorr and NGU test. I also saw an infect diseases doc who did herpes and HIV test. Tests were neg. However, after the doxycyc and metronidaz, I still had the discharge and the fungal infection. Urologist gave another 10 days of metronidaz and a urine dye to see if it's just urine. It's not urine, still clear discharge and I am 5 days through the second dose of metronidaz; I still see the discharge. My concern is not HIV, mentioned that in case the combiv and vir could have caused the discharge or the metronidaz not to work. Concern is discharge and not knowing the cause. While my doctor has not been able to test for trich, he said the metronidaz would have cured it. Describing the clear discharge better, a few drops every 4 hrs or so, and if I have not masturbated for a few days, more comes out in the few days after masturbation. I can feel it slowly collecting through my penis. I am not circumsized. Urologist checked prostate, it's fine; I am only 23. Is it another STD not checked for, like syphilis?
