I don't think of glossitis as a sign of primary HIV infection, but I suppose it can happen. But other viral infections, more common than HIV, also can do it. As you likely know, the risk of acquiring HIV from any single episode of vaginal sex is low, even if the woman is infected--which most likely was not the case.
1) "Could be" a symptom of ARS? I suppose so. But given the low risk nature of the encounter you describe, it seems unlikely.
2) HIV does not cause gas either upward or downward. Anxiety does, though.
3) See numerous other threads; search "time to postive HIV test". Two weeks is a bit early; probably only ~50% of infected people will have positive results that soon. It gets much higher at 3-4 and afterward.

Doctoer,
is muscle twitching a sign of ARS?
Muscle twitching is a normal, physisologic event; everybody has it from time to time. It often accompanies stress. To my knowledge it is not a symptom of ARS.
