The issue you raise seems to be something I’ve read a few times kicking about the forum. Unfortunately I don’t have the answer for you, but can provide that some “black” women, especially of athletic build seem to exhibit something of a tolerance toward some pheromones, though others may or may not have the same or increased effects.
Nick is another user who ran into similar issues…not sure how things are sorting out for him.
