You were told what the risks for HIV were. I'll repeat ONE more time for you. Unprotected penetrating vaginal or anal sex or sharing IV drug needles. Did you have those? No. Your scenario is not a risk. Air and saliva, both involved and both deactivate the virus. NO RISK.
Apparently you have already been told that you had no risk from the blowjob and that is is OK to resume sex with your partner. Feel free to move on.
Your question has been fully answered that you had no risk. We wish you the best.
