so you guys think after 2 years of possible exposure if i would've caught it it could've advanced so much that my body would stop creating hiv antibodies?
No! No! No! Quit questioning the outcome of both your negative tests! You are negative.
thanx guys. so you guys don't think there is any possibility that after 2 years if someone where hiv positive they would test negative for antibodies?
You have reliably tested negative. You do not have HIV.
Move on. Your antibody tests are 110% conclusive, assuming your unprotected sexual encounter 2 years ago is your only risk factor. It is true that people in advanced stage AIDS may test negative for antibodies b/c the immune system has become so weakened. This would take much longer than 2 years, however. Have a doctor look at your genital sores, which is the only alarming symptom you describe (could be due to anothe STD but definitely not HIV). See a therapist if your anxiety about HIV infection keeps up.
