Although those deomgraphics have a statistical higher risk of HIV than others, you should remember that ANYONE can have it and all types of people are positive so you should start using a condom.
However it isnt statistically likely that you will be positive, even if one of the those partners was positive so dont fret too much, good luck.
concerned? you had SIX exposures, didnt you?
if your test will be 3 months post your last exposure...then it will be conclusive
