I recently had unprotected sexual encounter (once) with a female I’ve known for a few years but not very well. After the encounter I started to feel symptoms of a uti, sting after urinating, low abdominal pain, tingling in penis. I went to see my doctor exactly 1 week from the encounter, and doctor couldn’t find any uti bacteria in my urine & prescribed cipro for 7 days as well as took another urine sample to test for Chlamydia & Gonorrhea.through a real time PCR test. I got my results back and was negative. I did not have sex again with my normal partner until after the 7 days of cipro. I went on thinking everything was fine with my normal partner until maybe 2 months after she started to feel symptoms of a uti same feelings I had, tingling, painful urinating, low abdominal pain etc. she also went to the doc who found no uti bacteria in her urine, (just like my Situation), he prescribed her antibiotics for 10 days and she got better. I was pretty freaked out so I went back to my doc to test for trich this time. I was  negative for trich on my urine Real time PCR test. My chlamydia & gonorrhea test was also Real Time PCR, how accurate are these tests? Also I’ve read something about Mycoplasma is this something I need to test for too? My doctor never mentioned this nor have I ever heard of it. I’m worried I might have given my normal partner some sort of std but I don’t understand how if my results are negative. No sores or bumps or anything at all just uti type symptoms. Is it just a coincidence that she got the same uti symptoms I had 2 months prior after my one time encounter with the other female? One last thing the one time female also did an std at her doc and was negative as well. What else could this be doc?

Most likely you have no STD and never did. Same for both your partners. Your initial symptoms didn't fit well. (By far the main symptom of a urethral STD infection is discharge; STDs rarely cause stinging after urination, penile tingling, or abdominal pain in males.) Further, it was wrong for you to be treated without better evidence of an infection, presumably without pre-treatment STD testing or you would have mentioned it. On top of that, you were prescribed exactly the wrong antibiotic:  ciprofloxacin is not recommended or used against any STD. It doesn't work at all against chlamydia, is not reliable for gonorrhea, and probably is ineffective against nongonococcal urethritis (NGU). But cipro has enough activity against them that it could make testing (after treatment) unreliable. Also, what does it mean that your doctor "didn't find UTI bacteria"? Did you have a urine culture? No other test can make this determination, and culture requries 2-3 days for results.

As for your partner's symptoms, it sounds like she might have had a UTI, but again I don't know how to interpret "no UTI bacteria". (Culture?) Although STDs can cause such symptoms, again this isn't typical. These are very "nonspecific" symptoms, i.e. they do not point reliably to any particular cause. Trichomonas generally doesn't cause any such symptoms at all in either men or women. But at least that test result was reliable, so you can be sure you don't have it. There are a few kinds of genital tract mycoplasmas. The onlly one that causes symptoms or disease is M. genitalium, but your symptoms don't fit; and most infected women have no symptoms at all.

Having said all that, I'm glad to hear your one-off partner from two months ago has had negative testing for STDs. That result adds to the evidence that none of this was due to any STD at all. 

My advice is to do nothing more for now and that you and your regular partner continue your normal sexual lifestyle and practices. If you develop urethral discharge, or if your or your partner's symptoms reappear, you should both be evaluated by a doctor more experienced in STD management than the one you saw previously, and have a comprehensive STD evaluation before any antibiotics are prescribed or taken. Most likely none of this will come to pass; as I said to start, I doubt any of the three people involved have any STD at all.

I hope these comments are helpful. Let me know if anything isn't clear.

Thank you for your response DR. Handsfield 

No my doctor never sent the urine off for a culture for either of us, he told me my urine looked fine & that there was no need to send it off for a culture even tho I asked him if he could. His exact words were “I can almost tell when someone’s urine is goin to come back positive for bacteria, based on the little test that he does” not sure what simple test he did to check my urine in his office but it took 30 mins max. As for the cipro, I took that after I left my urine sample to be sent off to the lab to be tested for chlamydia & gonorrhea, so the cipro Wouldn’t have affected the results. Although I am cornered that by taking the cipro for 7 days if there’s a chance it could have affected my second urine test this time for trich, chlamydia & gonorrhea 2 months later. So you’re saying I could have very well had a uti since my urine was never sent off for a culture? That’s pretty upsetting to me that my doctor would make that type of decision without testing, it has caused a lot of unnecessary stress and anxiety. There’s one thing that is forsure is the person I had the one night encounter with called me and had me meet her at the doctors office when they said her results were ready, I was able to see her test results for chlamydia, gonorrhea, hep b, hep c and hiv all come back negative as well  as a no growth, final report urine culture.So that should mean that there’s was no std transmitted from her to me correct? Meaning this was most likely a uti possibly from her giving me oral? Adding to that my normal partner didn’t get these symptoms until 2 months after my one night encounter with the other female. If this was a serious std like chlamydia, gonorrhea or trich would it take 2 months to transmit or show symptoms?

Having said that cipro can interfere with gonorrhea/chlamydia testing, that's only for 1-2 weeks. Your negative tests at 2 months prove you were not infected at that time. And cipro has no effect on trichomonas; that result also was reliable.

Correct, your one-time partner's test results are conclusive. Your conclusion about the timing of your regular partner's symptoms also is correct.

So my conclusion and advice above is unchnaged. There is no chance you or your regular partner have any STD from your dalliance a couple of months ago.
