Your symptoms are not typical for any STD and I am confident you have no infection of any kind. Certainly mycoplasma or ureaplasma are not responsible. You describe nothing to suggest reactive arthritis. There was no need for the various antibiotics you have had -- but in any case, continued symptoms after them is confirmation of no infection. You are correct in your interpretation of the HIV test results, and in you were not at significant risk for HIV.

All things considered, I'm fairly confident you're suffering from genitally focused anxiety. I'm not a believer in anxiety or other emotional origins of physical symptoms. And I'm not saying  your symptoms are merely "in your head". However, anxiety -- e.g. resulting from a sexual decision and experience that you regret -- certainly can magnify trivial symptoms or even normal body sensations that you otherwise would ignore or not even notice. And you might google "chronic pelvic pain syndrome" (CPPS). The information from the Stanford University dept of urology is very good. I'm betting you'll find a lot of information that resonates with your symptoms. As you will see, many (most? all?) cases of CPPS would once been considered chronic (non-infectious) prostatitis -- although it is now know that the prostate may not be involved at all.

Please stop testing for any and all STDs, and do not attempt any further treatment, at least not without professional adivce. Consider seeing a urologist -- and perhaps printing out this thread as a framework for discussion.

I hope this information is helptul. Let me know if anything isn't clear.

Since I have two follow ups, and I couldn’t fit everything in the initial question, I suppose I’ll just ask even though I’m sure it doesn’t change anything.  I suppose my only point of confusion is that my girlfriend had very similar symptoms along a similar timeline as myself.  Does this not suggest a shared infection of some kind?  Granted, she was menstruating at the time and does suffer from anxiety more so than myself and was anticipating having an std.   Also, just out of intellectual curiosity, what is the explanation of the change in stated conclusiveness of ag/ab tests from 4 to 6 weeks? Are there specific outliers or just randomness?   CPPS has been something I’ve been reading into as well, thanks for the recommendation.  I do have an appointment with my pcp this week to explore these seemingly nerve related pains, I’m hoping it’s just a pinched nerve or an exercise related injury.  I should stop playing internet doctor for the sake of my own sanity.  

The change in our advice about 4 vs 6 weeks as the window for the HIV AgAb tests occurred almost 3 years ago. Nothing mysterious:  just improved data becoming available.

Finally, your internet comment:  The famous statistician Nate Silver (see fivethirtyeight.com) wrote a book about statistics titled The Signal and the Noise. In it he states (approximate quote) "Give an anxious person a computer with an internet connection in a dark room, and soon he'll think his common cold is the bubonic plague." Anxious persons tend to be drawn to information that enhances their fears and to miss the mroe reassuring information that also is present. Sound familiar?
