As you were advised, you had no risk for HIV. Therefore, any symptoms you are experiencing are not related to HIV. There isn't anything more to say about this no-risk event.
********** THREAD CLOSED **********
You had zero risk so you don't need to test. Condom failure results in a large visible rip down the seam, so you and she would have noticed it.
HIV is instantly inactivated in air and also in saliva which means it is effectively dead so it can't infect from oral. So those are 2 reasons you had zero risk. Double zero risk. It doesn't matter if you and he were bleeding at the time either because it is effectively dead.
Only adult risks are unprotected penetrating vaginal or anal sex or sharing needles that you inject with. You used a condom so had no risk here either.
Even with blood, lactation cuts, rashes, burns etc saliva and air do not allow inactivated virus to infect from oral. The above HIV science is 40 years old and very well established so nothing you can add will make it a risk.
Your symptoms are self-diagnosed, so likely to be incorrect, especially something like the cough congestion with no cough that seems real to you in your terrorized state thinking you might be dying.
you interact with other people so the odd sore throat is to be expected.
