Not HIV: It sounds like you're worried about HIV, but your negative test proves you don't have it -- and HIV is rarely if ever transmitted by cunnilingus (oral-vaginal contact). Lost of other things could be causing your symptoms. Has oral thrush been professionally diagnosed? You can't know just by looking or by your symptoms. See a doctor, perhaps an infectious diseases specialist. Good luck.
