To start, I have read over many posts concerning oral sex and know what the theoretical risk is BUT like many others feel like I am an anomaly. I am a 29 yo homosexual man that had oral sex with a young man on April 9th. It was 90% insertive but I gave him oral back for about 2 minutes- he did not ejaculate. AFTER the encounter he informed me that he was indeed HIV+ and reassured me that he was on ART and that his viral load was undetectable; he stated that he was proud of himself for never missing a dose. After asking, he gave me lab results from July '17 and another from April 24, 2018 with undetectable viral loads. I have been feeling off for about 2 months now and was recently diagnosed with Mono after confirmation with the heterophile Ab test. My concern is that about a week following the encounter, I developed an oral ulcer and varying stools- some days loose and others constipated, which I believe has resulted in an anal fissure. I was also diagnosed with IBS years back but haven't had many issues with it. In addition, I have a splotchy redness on both of my forearms that comes and goes and feels like it burns sometimes. It is not raised or bumpy, and everyone tells me I'm crazy and thats it's not even there. I am convinced this is ARS because everything i read states that oral/anal ulcers are uncommon with mono and common with ARS, as well as this redness/burning of the arms. I have no fever or sore throat but my anxiety/stress has put me in a depression- when I wake up in the morning all I can think about is going back to sleep later on. I have also read that a positive mono test can be a false positive for ARS. I know testing is the only reliable indicator but I don't want to test until I know the results will be accurate. If anyone could provide some reassurance it would be greatly appreciated- I think I am literally worrying myself sick. I like this man and I want to believe he wouldn't put me at risk, but at the end of the day I don't know him well.
What is my risk from this encounter?
How common is a false positive mono test when you actually have ARS?
When is a reliable timeline to test with 3rd and 4th gen?
Can anxiety or mono cause ulcers/redness/tingling/burning/GI problems?
What is the likelihood that this mans viral load was undetectable on the 9th with a result from the 24th?
Thanks in advance, going crazy.
