Welcome to the Forum. I'll be pleased to comment. Let me first say that I doubt that you penetrated your partner- had you penetrated her, you would have known if. Even if you penetrated her however, a single, brief exposure would not put you at high risk for HIV- most commercial sex workers do not have HIV and less than 1 in 1000 sexual exposures to infected partners lead to infection.
Having said that your exposure was low risk, I will acknowledge that the signs of the ARS are a flu-like illness occurring about 2-6 weeks after exposure and presenting with high fever (your fever was not very high), muscle aches, sore throat, and sometimes a rash and/or diarrhea. These however are also the same symptoms that are caused by many other, non-HIV, non- STI viral infections such as influenza and when persons with this set of symptoms has been studied, less than 1% of them turn out to have HIV.
The ARS is a syndrome which can be mimicked by many other illnesses. That is the reason we have tests. If your current symptoms were due to HIV, an HIV test would be positive at this time. I suggest that you go and get tested to prove to yourself that this is not HIV. A negative result will mean that your symptoms are not due to HIV.
I hope these comments are helpful. EWH
