This question may be from anxiety, but just wanted to ask to be sure. Earlier, I asked about my situation where I kissed and both gave (less than 10 seconds; did not receive ejaculation) and recieved oral sex to a older man; I have not had any symptoms and he told me he tested a month later with all negative results. Since my first question, I got tested for HIV, Chlamydia & Gonorrhea (oral and urine), syphilis and hep b&c approximately 2.5 months after the original encounter. Fortunately, they all came back negative but I'm still concerned about one thing. Is it possible that I did catch oral gonorrhea and it cleared before my test? I'm concerned because I had 2-3 other oral interactions with my partner in the 1.5 months after the male oral interaction and I'm concerned I potentially spread something to her before it could have potentially cleared up before my test. Again, I have not had any symptoms and everything tested negative. Apologize if this may be a waste of time, but just want to ask for reassurance. Thanks.  

The chance you were infected at all was extremely low; re-read your previous discussion. (We came up with a possible chance of gonorrhea of one in 200,000.) Chlamydia risk was zero. In theory, you could have had gonorrhea that self cured in the 2+ months after exposure, but I would estimate that chance as under one in millions. Syphilis for sure is impossible; your test at 2.5 months definitely would have been positive if you were infected. (Syphilis does not self cure like gonorrhea does and a negative blood test more 6+ weeks after exposures is 100% reliable.) Going back to gonorrhea, absence of urethral (penile) discharge and painful urination is nearly 100% proof you weren't infected. As for oral gonorrhea, it is not easily transmitted to partners by either kissing or cullilingus (oral-vaginal contact).

All things considered, there is no realistic chance you have any STI from the events described or that you have put your regular partner at risk. You should not have any more tests.

I hope this helps. Let me know if anything isn't clear.
