Thank you for you question.<\/p>\n
It is not possible to be immune to HIV. What you are describing\u00a0was seen in the earliest years of the epidemic, in the partners of men with haemophilia who had been infected with HIV many years earlier. This is thought to be explained by developing a strong local response to one virus, but I think this is still just a theory.
\nYou may have a genetic protection against HIV due to a genetic mutation (called delta 32 deletion). Even if this is the case, and less than 2% of Caucasians have this, there is no commercial test, and it still may not guarantee protection.
\nPerhaps most likely is that you could just have been lucky in not having caught HIV after many exposures. Sometimes it might take hundreds of exposure though before someone is unlucky and becomes infected. So using condoms from now 0n would probably be recommended by most healthcare professionals.\u00a0\u00a0Some people with a genetic mutation called delta 32 are less likely to catch HIV but even then it is still possible to become infected. You may have just been very lucky so far.<\/p>\n
