Thank you very much doctor, that is probably the exact answer I was hoping for. I definitely feel much more at ease! Thanks again.
Welcome to the forum. I think I can help.
Almost everything you say works in your favor. First, the exposure itself was very low risk. Even if your partner has HIV, such a brief anal sex exposure almost certainly wasn't sufficient for transmission. (I'm assuming anal -- you don't say -- but if it was oral, well that's zero risk anyway.) Second, people rarely lie about HIV status when asked directly, so it is unlikely he is infected. Your objectivity about believing him is obviously being affected by your emotional response to a sexual decision you regret. Third, if he had HIV, taking PrEP meds would make him non-infectious.
And finally, your negative DNA test is around 95% conclusive. The oral fluids test is meaningless at 2 weeks, but for the reasons above, that doesn't matter. Combining all the information available, you can be 100% certain you did not catch HIV. In fact, had you asked me ahead of time, I would have advised that you shouldn't even be tested, and I see no need for further testing. If you have a regular sex partner, you can safely have unprotected sex without fear of transmitting HIV.
If despite this reassurance you feel you need an absolutely definitive blood test, have any HIV antibody or antibody-antigen ("duo") test at 4 weeks. It can be either a rapid or lab-based test, as long as the specimen is blood. Another oral fluids test won't help until 3 months. (Many people, and the official advice from some agencies, is that 3 months is required for definitive testing. For the blood tests, that is no longer true. However, it remains true for the oral fluids test.)
I hope this has helped. Best wishes-- HHH, MD
and I'm sorry I forgot to mention the gentleman also told me he was on PrEP, still not certain I believe him.
