Your sore throat doesn't mean anything in regard to HIV.
You cannot catch HIV through intact skin, no matter what HIV infected fluids it contacts. Do you really imageine that in the 30 years of the known world-wide HIV/AIDS epidemic you will be the first person infected who didn't have a traditional risk factor? The virus is very hard to transmit! For example, te household members of HIV infected people, sharing bathrooms, toilets, kitchens, and eating utentils for years on end never catch HIV (assuming they aren't also sex partners of the infected person).

You came here for reassurance, and I gave it. Please accept it, and for goodness' sake don't argue about it! The whole idea is to help you relax and mellow out. I hope you can do so. In any case, I won't have any further comments or advice.
