The way to inflect STDS when accpeting oral sex

Dear Doctors, thanks for your answer first, which make me relexed from HIV. But now I am still worried about STDS, especially syphilis and NGU after my receiving oral sexual from a women. Although I learn that the risk is very low, but I can't make my safe until now. Durning the days, I had a throat pain and cough for several days. Tonight, a little pain on my mouth. I am very very dispressed. I always doubt that I have inflected the syphilis or NGU.
Now I am eager to know how syphilis and NGU inflet a male from the woman's mouth, only being given oral sexual without protect and ejaculation into her month.
Thanks again.

If you had a STD it would infect your penis, nothing to do with your mouth and throat. Your risk was low and at this point no reason for testing or worry.

Thank you very much, Vance. So if I am inflected, the symptom will be found on penis, but not month?
Thanks again.
