I'm a 34 year old sexually active gay male. I test regularly for HIV and currently test as negative (via Oraquick).
About a week ago, I had a multiple sexual encounters with another male (who also tests and assures me he's negative). The main risks involved, if any, would be giving oral sex to completion multiple times, including swallowing, a little rimming, as well as unintentionally getting some of his semen into my eye. From my understanding, while these are of course not no-risk activities, they are still relatively low risk activities (with some even possibly being theoretical). I of course plan to continue regularly testing to assure my negative status.
That said, what concerns me is 4 days after (the first) encounter, I developed a sore throat (branching to my ear), fever (reaching 103.4 at its highest), general achiness, and alternating periods of chills and soaking sweats. The fever lasted 3 days or so, and this is the 5th day and I'm feeling quite a bit better, though not 100%. There was no vomiting (weirdly appetite stayed intact), diarrhea, or skin rash that I could see.
1.) Would this be consistent with ARS? My main worry is I don't know anything else with these symptoms currently going around, but I was traveling. I know I've read ARS onset usually happens between 2-4 weeks, so this seems a little soon for ARS, and I've also read it lasts 1-2 weeks generally, so this seems shorter duration as well. In addition, a few sites list the fever with ARS as being mild (102 or so), and mine was higher than that. So I'm wondering if any of this rules out ARS?
2.) Sometimes when I eat citrus, my tongue tip is sore. There is no bleeding and no sore I can see...it's just a feeling. Does this make oral sex any riskier? I did have a bit of this looking back, but it's a fairly common occurrence with me and not related to poor oral hygiene (there's never any blood or "open sore" aspect that I can see).
