I had protected vaginal sex with a girl in February and gave her unprotected oral sex. I'm from the UK she is from the US) The condoms were fully intact.  After the oral sex, she bit my lip while French kissing, leaving a mark and perhaps drew a bit of blood from me. Is the cunnlingus (from replies I've read on the forum only a handful of cases attributed to transmitting HIV to the giver and in regard the cut from her lip biting me, I'm unsure)

3 - 4 days after I developed what I presume was a cold which lasted a further week (sneezing, nasal drip, minor cough were my symptoms). I don't think this fits the timing or symptoms of ARS but I'd like to check that too.

Many thanks

As in your previous questions 3+ years ago, this sounds like a very safe exposure. Getting a lip bite did not materially elevate your risk of any STI, with the possible exception of HIV or other blood borne viruses like hepatitis B. But the chance a partner like this has either of these is near zero. And I'm not aware of ANY scientifically documented cases of HIV transmission by cunnilingus; I think the few reports you allude to reflected unsupported patient claims or beliefs, not proof of such transmission.

And indeed 3-4 days is much too soon for ARS, and the symptoms don't fit:  acute HIV infections don't cause nasal drip, congestion or sneezing. You caught a cold -- or maybe COVID (for which you should be tested). But I really see no need for concern about (or testing for) HIV or any other STI on account of the events described.

I hope these comments are helpful. Let me know if anything isn't clear.
