""The word whore is often used metaphorically to criticize a woman for using her erotic charms for "selfish" reasons, such as wealth and power. ""

Under this odd definition, I suspect there is no scarcity of female whores in the world.

Such is the plight of many unfortunate females- not be born looking plain. Same goes for many of the other females seeking to use whatever advantage they may have to "get in on" the significant share of the global wealth and power that males hold. Oddly, few males would be called whores, for using whatever advantages they may have to reach similar goals (that may seen by some others, as selfish, or not).
