Welcome back to the Forum. In preparing to answer your question I happened to look at some of your 14 prior posts over the past few years. Not only has your partner had other unprotected sexual encounters but so have you. I will address your question but I would also suggest you work to sort out why your concern is so great? - your partners or something else.
Your risk is low. Presuming your partner was not an IV drug user, the risk of an American woman in NYC who is not an IV drug user having HIV is less than 1 in 1000 and each episode of intercourse also carries a risk of infection of only 1 in 1000 exposure even if she was infected. Your exposure was a low risk exposure.
As for your symptoms, the world is in the middle of an influenza pandemic and other varieties of non-HIV viral infections also are far, far more common than symptoms due to HIV. As we have said repeatedly on this forum, for a person to worry about symptoms as a sign of acute HIV infection is really a huge waste of time.
Bottom line, your risk is low and your symptoms do not change this in any way. My advice would be for you and your partner to go get tested. When you each have negative tests at this time, you can stop worrying. EWH
