HIV transmission - Oral sex and precum

Hi Doctor,
Approximately two days, I had gave unprotected oral sex to another man. I don't know his HIV status, and I am worried about the possibility of HIV transmission. I only performed oral on him for 3-4 minutes tops, and i only came in contact with his precum. From what I have read online, I understand that precum can carry HIV, and this is why I am worried. When I got home after the incident (12am) I did not brush my teeth as to not disturb my gums, but I did use mouthwash. However, at 7:30am I brushed my teeth. I did not notice my gums being irritated or inflamed, and I generally have good oral health. Two days after the incident (which would be tonight) I flossed my teeth. I haven't flossed in a while, and doing so irritated my a part of my gums and they bled a tiny, tiny bit. 1) What is the possibility of transmission at the time of the incident, given if he was HIV positive and 2) is it possible for HIV to survive in the mouth long enough after the incident to infect me after brushing/flossing? I hope that made sense..I am freaking out about this.

Sincerely,
Worried

theoritically speaking brushing just before oral could be considered a risk as it can expose bleading gums to precum or sores in the partner, but not after, since saliva has enzimes and proteins that kill the virus,also mouth is hostile, also saliva without your attention is repeatedly washed down to ur somach so again stomauch is hostile to the virus and the enzimes kills it hence oral is considered safe, some experts put it as 1 in 10000 thats almost zero.... With or without precum or bloody mouth... But u can get stds.... Watchout for that!

I had oral sex last week with a guy I met on the internet, he has braces and because of the way he kisses me I failed to notice even failed feel that he bit my lips and caused it to bleed. Not noticing the bleeding I gave him oral sex for 4 times, but i did not allow him to ejaculate on my mouth, he masturbated after the oral sex. I am just worried if precum can transmit virus and infect my bleeding lips.

Hello, there!
First of all, even if the other guy was positive, there is no significant risk of contracting HIV after performing oral sex on him, even if he had ejaculated in your mouth, which is not the case here.  The estimated risk of someone having unprotected receptive oral sex with a HIV positive man is less than 0.04% (less than 1 in 2,500), not knowing his status would reduce this to less than 0.006% (less than 1 in 17,000).  Even if you had some amount of precum in your mouth, your saliva would destroy the virus immediately.  Therefore tha answer to your second question is also no.
Best wishes,
Dr Jose Gonzalez-Garcia

**2) Is it possible for HIV to survive in the mouth long enough after the incident to then later infect me after brushing or flossing?*** (that time being the time from the incident to brushing of the teeth - 8hrs or time of incident to flossing - 48hrs
