Oral is zero risk because hiv is instantly dead in air or saliva which is all that is in a person's mouth other than possibly some blood but it's hiv would be already dead in there.
You could do what you started to do any time and never get hiv but you can easily get Covid.
The only risks for HIV are having unprotected vaginal or anal sex or sharing IV drug needles. Oral sex is not a risk for HIV transmission as saliva and air inactivate the virus. So, you do not need to worry about HIV as you had no risk.
Any other std risk from this? The lady literally tried to give me a blow job and i pulled away in 2 seconds?
