Scientifically speaking, if the females pussu smells or tastes foul it's usually caused by bacterial infection such as bacterial vaginosis which is caused by an overgrowth of anaeorbic bacteria.
According to most research studies I've heard of so far, bacterial vaginosis is not a racial bacterial infection.
So scientifically speaking, you're eating some dirty white girls pussu, and you need to tell her to wash that shit more thoroughly.
