Thanks for apparently reading other discussions with similar questions, which I assume from your understanding your exposure was low risk:  I agree. Also thanks for acknowledging your OCD and anxiety. As for your sy mpotms, they are typical for anxiety elevating your awareness of trivial symptoms or even normal body sensations that otherwise would not be bothersome or maybe not even noticed. When an STI or other lower urinary tract infection is present, the symptoms never are intermittent but are present continually; that's one of the main factors arguing against an infection. So does absence of burning during urination and visible urethral discharge. (I'll also point out that when someone suspects their own symptoms are due to anxiety or other psychological factor, usually they are right!)

From a medical/risk standpoint, you do not need to be tested. On the other hand, I fully understand that testing for reassurance alone -- even when the risk is nil -- can be beneficial. Many persons in your situation are reassured as much or more by negative test results as by professional opinion, no matter how expert. So although I personally would not be tested in your situation, feel free to do it if you wish. Sufficient time has passed for reliable results for standard testing in this situation (i.e. a urine test for gonorreha and chlamydia).  You also could have blood tests for syphilis and HIV 6 weeks after the event, but these are so exceedingly unlikely that I don't think it's worthwhile even for reassurance. But this too is an option if you wish.

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