Welcome to the forum and thanks for your question. I can help. I reviewed your discussion about all this on the HIV community forum and agree with the reassuring responses you had there (but which you seem to have trouble accepting and believing).
You can be certain you do not have HIV and that something else explains your symptoms. Of all the information provided in your question, by far the most important is your negative HIV test results. Given the specific tests you had and their timing, they prove you don't have HIV. When testing is done sufficiently long after exposure, the results always overrule exposure history, symptoms, and other lab test results.
Given that fact, I'm not going to spend any time anlayzing your symptoms, except to say they are not as typical of ARS as you seem to think. In addition, the sexual lifestyle you describe is not especially high risk for HIV, and it statistically unlikely you were exposed to it. But I'll say the important information once again, in the hope it will sink in: even if you had the highest risk exposure imaginable, and even if your symptoms and various lab tests were highly suggestive of ARS, the HIV diagnostic test results tell the truth. And by the way, CBC results naturally vary within the range of your results; the differing WBC levels at various times are meaningless.
In case you are interested in more discussion about HIV test results and their reliability at various times after exposure, see the following recent thread, as well as the other threads whose links are provided in it:

In other words, I am in exact agreement with your "Doctors [who] doubt HIV", and I am confident your problems have nothing at all to do with your sexual partners or your sexual lifestyle. Continue to work with your doctors about what's going on, but try to stop worrying about HIV. You don't have it.
Good luck-- HHH, MD
