Precum and oral sex

[neara]

Two months ago I had sex with a boy, but with condom. The thing I am concerned about is the oral sex I gave him - he didn't ejaculate in my mouth, but I could have swollen some of his precum. If there was HIV, was there a chance of infection? I didn't have any cuts in my mouth. Could the saliva "kill" the virus? Anyway, I just hope hope he is not infected. He had many partners (girls) before and wasn't using the condom with all of them, but with the majority.
Thank you for your answer.

We are talking about a cut big enough where you would be getting medical treatment not doing anything sexually.

Ok. Another question came up in my mind: how big or deep has to be the cut in the mouth to get infected with presemen during oral sex? I have a dental brace and micro cuts are possible, but nothing bloody or big that can be visible with the eye.

Saliva as different proteins and enzymes that renders the virus inactive.

Thanks. I have another question: can the virus be transmitted via saliva, if the infected saliva enters directly the bloodstream? Or is the virus concentration in the saliva too low?

Oral sex is not a risk with HIV due to one of the reasons you stated...saliva deactivates the virus. It breaks it down and does not alow it to get into your system.

You didn't have a risk even if a condom had not been used.
