From my experience a fair amount of girls are willing to go bisex if "the vibe is right",
as in most of other parts of the world a guess..
Since the society here was, and still is a bit, traditional, young girls are eager to experience and explore new things and people. They like the dare of new.
Some of girls like to play ice queens - they want a man to show his game and to "conquer" them. They like dominant man that is secure in himself and natural.
But not aggressive in approach.
So, with a charm, confidence, humour and with some girls by just being black (that desire for new experience) I doubt you will stay pussy free.
