You describe a near zero risk exposure in regard to HIV, as well as other STIs. Most sex workers do not have HIV, and when they do, even without a condom the chance of transmission from a single episode of unprotected vaginal see is around once for every 2,500 encounters; with a condom it is near zero, and getting vaginal fluid on pubic area skin -- even with recent shaving -- is zero risk. Oral sex also is zero risk for all practical purposes.

Finally, your negative RNA test at 11 days is 90-95% reliable. That does not mean there is a 5-10% chance you have HIV. Before being tested, the chance you had caught HIV probably was no higher than one chance in 250,000. With your negative test result, 90% reliability means the possibility you have HIV is now about one in 2.5 million. For 100% certainty, also have an AgAb (4th generation) blood test 4 weeks after the exposure. The negative result will make it certain you didn't catch HIV.

So all is well. Perhaps you also would like to know that in the 20 years of this and our preceding forum, with thousands of questions from people worried about possible HIV exposure, not one forum user has yet reported that they eventually tested positive. You won't be the first!

I hope these comments help you move on without worry! 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 (as you were for this exposure!).
