Concerned about exposure and primary HIV symptoms

[Jefferso]

I had an unsafe oral intercourse with a man, during which he ejaculated in my mouth. I performed this while having throat inflammation (perhaps with sores, not sure about that). The question is: what risk I had to contract HIV? (the status of a partner should be considered unknown).
There is also a number of symptoms, which started emerging exactly a week after the intercourse and kept piling up during one week: first, fever (up to 37.5C), loss of appetite, night sweats, bouts of severe fatigue; this was followed by some small ulcers in the back of my mouth, muscle pains (especially shoulders, arms, back and tights), and white thrush on my tongue. Could these all be signs of primary HIV? Can they appear so soon (1 week post-exposure) and pile up gradually rather than appearing all at once?
Many thanks!

We cannot help the incorrect information that you read elsewhere.

I've read a lot about HIV transmission through oral sex. Opinions range from "no risk at all" (like yours) to more nuanced "much lower risk than unprotected vaginal/anal sex, but still not zero-risk" (some estimates give chance of 1 to 5,000) and to even more nuanced that the risk increases if: 1. mucous membranes in mouth and throat are exposed to HIV+ person's semen (or blood, if there are sores on penis); 2. if a receiving partner has sores, cuts, inflammations, bleeding gums and other conditions making it possible for virus to enter bloodstream. In my case, I had inflammation and contact with semen. Would you still stand by your judgement that I never had an exposure?

You never had an exposure, HIV is not transmitted by Oral sex.
