This was a zero risk event, for a few reasons. First, if "slightly higher HIV rate" implies an industrialized country and other similarities to the US, the chance of having HIV in any particular sexually active straight male is extremely low. Second, HIV is rarely if ever transmitted sexually between males and females without penetration (probably) and without ejaculation in the vagina. Third, oral sex is zero to low risk. There has never been a proved case of HIV transmission by cunnilingus, to either the oral or vaginal partner; nor any proved case for the penile partner in fellatio. A few cases probably have occurred for the oral partner in fellatio, but at a rate CDC once calculated at 1 in 10,000 -- which is equivalent to giving BJs to HIV infected men once daily for 27 years before virus transmission might be likely. And even this probably would depend on ejaculation in the mouth, which apparently didn't happen.

Is testing warranted? From a strictly medical/risk perspective, no. While I cannot guarantee the risk was zero, the chance you were infected probably is no higher than one in a billion, and if I were you, I would be comfortable with my next annual routine screening test. That said, I'm not you -- and you wouldn't be here if you weren't nervous about it, and that won't necessarily be resolved by my expertise or by the statistical facts. So it's up to you:  if despite this assessment you're going to lose sleep until you have had a negative test result, by all means do be tested. You can have a nearly conclusive antigen-antibody (AgAb, "4th generation") blood test 4 weeks after the event and a truly 100% conclusive one at 6 weeks.

I hope this has been helpful. Let me know if anything isn't clear.

That completes the two follow-up exchanges included with each question and so ends this thread. I hope the discussion has been helpful. Best wishes and stay safe.
