The level of ignorance on here is sometimes funny, in this case it is sort of scary. Having just finished the notes from my AM HIV clinic, here are some facts:
-No disease can be diagnosed by a 5 line text description. No disease manifests itself in idenical ways in each person. The symptoms the OP poster described could easily be due to: strep, mononucleosis, a non-specific viral upper respiratory infection, hsv (1 or 2), HIV, lymphoma, and many others.
-Chances of contracting HIV from a single episode of insertive intercourse is estimated at 0.05 to 0.07% (2008 Sanford Guide). Risk goes up 10 fold (~0.5% for receptive intercourse). Having other lesions (syphilis, hsv, etc) is felt to the risk by an unknown amount.
-HSV 1 and 2 are clinically indistinguishable. Both can cause oral and genital lesions, as well as meningitis, encephalitis, and other more invasive forms of disease.
-Testing now and again in 2-3 months is a good idea (yes the first test may be negative from this exposure, but some people convert more rapidly than others).
-Getting HIV now is not the end of the world (not that I think you have it). There are approximately 30 drugs that can be used, many very tolerable, including one that comes in a one pill once a day form. People now live with HIV, and although the natural history is still playing out (effective therapy really started in the mid-90's) we think people can live jkust as long a life with teated HIV as they would have otherwise.
-Safer sex is a good idea.
