Welcome to our Forum.   I'll be pleased to comment.  This was essentially a no risk event despite the rather high risk nature of your partner. Most commercial sex workers do not have HIV and even if your partner did, your vaginal sex was condom protected and acquisition of STIs of any sort, including HIV from cunnilingus is nearly unheard of.  There are VERY rare cases in which person have acquired gonorrhea of the throat from performing cunnilingus but this is extraordinarily rare.  There are no known cases in which HIV has been acquired through cunnilingus, even when the recipient is menstruating.  Personally, I would not worry at all about this exposure however if you desire to test to be 100% sure that no STI was acquired, the only STI that I would recommend from a medical perspective is a throat test for gonorrhea.  There is no medical reason for blood tests for HIV, hepatitis or syphilis and no reason for penile testing for other STIs. 

I hope this comment is helpful.  EWH

The symptoms you describe are not suggestive of the ARS which typically presents with high fever, severe muscle aches and sore throat and sometimes diarrhea or a rash.  Your symptoms do not suggest the ARS to me and are more compatible with an everyday "cold" or URI which coincidentally occurred following the exposure you described.  Give the nature of your reported activities, I would not be at all concerned about the possibility of HIV and rather would urge you to move forward without concern.  Take care.  EWH
