Five months is more than enough time, no matter what HIV
test was used, in India or any other country. Whatever is causing your symptoms, it isn't HIV
. Anxiety or depression sounds like a good bet.
Also, nobody has ever been proved to catch HIV by receiving oral sex. NEVER ANYWHERE IN THE WORLD IN 20+ YEARS OF AIDS! There have been such reports, but I stress "proved". If it occurs, it is too rare to measure.
