It makes no difference where it was,what you engaged in is not a mode of transmission for HIV.
NO South Africa, that is why I am so concerned about my risk as there is a real strong posibility that she was HIV or could of had another std which would make getting HIV easier to catch.
zero, and it seems you already know how to protect yourself from hiv.
At no time did you ever have a risk of HIV infection from the activities you engaged in.You're safe.
