81 days is close to 84 days which is 12 weeks. This is conclusive. You don't have HIV.
I agree with baller, you don't need to retest.
If the place where you tested told you that 81 days is ok, so trust them and dont worry more, and for the 1rst question, HIV2 is not common anyware outside some countries of Africa. Olvidate amigo.
Why is her race an issue?Should the CSW go get tested because of your race/nationality? People contract HIV from all races. While some countries have higher percentages of infection , people still become infected outside of Africa. Whether it's uncommon or not plays no real baring on things. While I agree with TEAK .. If your going to be having sexing just wrap it . No matter what the persons race is.. Whether she's a CSW, regular working chic ,man or whateva just have safe sex.
