On a drunk night in the beginning of August I received unprotected oral sex with an unknown woman. Then we had protected vaginal and anal sex. 5 days later I noticed a slight clear discharge from my penis and also felt a slight burning sensation. I went to leave a urine sample the day after to get tested for Chlamydia and Gonorrhea. Both came back negative.
On day day 11 I also started to feel some pain in my right testicle. I took 2 g azithromycin that I had bought online. On day 13 I could not see any improvement and went to see a urologist. I had trace of blood in my urine and the top of my penis was a bit red. He gave me a shot of ceftriaxone and a 10 days cure of doxycycline. He also took another test for Chlamydia, gonorrhea, and HSV.
The testicle pain started to clear up a few days after and now I can hardly feel it. Today the doctor called and said that all tests came back negative. It is now day 20 and I still have the same amount of clear discharge in the mornings and sometimes a slight burning sensation. I have 3 days left on the doxy. He told me to call him if I still had symptoms after that.
Now some questions:
1. Can I be sure that it is not Gonorrhea I'm dealing with or could I have false negative two times?
2. If it's not Gonorrhea, is NSU most likely? Should not the antibiotics I took clear that up?
3. Is trichomoniasis a likely/possible cause?
4. What else can it be?
5. Do I need some other antibiotics?
