The oral was me receiving.
You could have NGU, which is an infection in the urethra, and can be caused by normal mouth bacteria. Are you getting the 10 panel test from STDCheck? They don't include NGU.
And you don't need all that. You had protected sex, and unprotected oral. You're at risk for gonorrhea, chlamydia (this is unlikely, but possible), NGU, syphilis (uncommon, but possible, and doesn't fit your symptoms), and genital herpes type 1 (if you don't already have hsv1), possibly genital herpes type 2.
The 10 panel from STDCheck includes hepatitis A, B and C, and while in theory you can get hep B from oral, there hasn't ever been a documented case of it. Hep A is spread through fecal matter (poop), and is almost always spread through contaminated foods. Hep C is spread only by blood, usually by sharing needles for drug use. If A and C are spread sexually, it's rare and is almost always by unprotected anal sex.
Oral sex is much lower risk than unprotected sex, but it's still possible. I'd rather you go to an STD clinic, where they can check your urine for white blood cells, which is how NGU is diagnosed. If you have NGU, your partner needs to be treated, too.
I don't know where you are, and what's opened and closed because of covid, but if you're in the US, call your local health dept and ask about STD testing.
That is interesting. I wonder what has made it possibly more common than before.
Yes that is correct, it was unprotected. I did tell her to get tested and seek treatment. She can be skeptical so I wanted to know the odds of transfer.
