So, it's been a while since you posted. I'm going to remind you what the risks of HIV are in adults. They include unprotected vaginal or anal intercourse with penetration or sharing IV drug needles. What you describe is not a risk. Air and saliva inactivate the virus. So, no. This is not a risk.
You received this answer in 2016. "I reviewed your previous posts on this site and noticed that you have been advised many times that oral sex - protected or unprotected - is no risk" https://

You have asked this question another 4 times since 2016 too. I suggest you stop going to these CSW since it makes you anxious afterwards. Or else seek therapy for your hiv obsession so you can live a normal life. btw if she has Covid you likely have it too, so you are focusing on the wrong virus.
