An evolutionary biologist was once asked, what is the evolutionary advantage to women having stinky vaginas?

He replied: Back when humans started to evolve on the plains of Africa the men would leave the women while they were out hunting for food. Those women with really stinky vaginas survived because lions and other massive predators were not able to stand the smell so they left them alone.

I know its a joke but I wonder if maybe there is some truth to it lol. I guess soon a feminist will show up to lecture us about this. They always show up when the topic is big vaginas or stinky vaginas.
