“Sluts” and “whores” are often words used interchangeably, but to my mind they have rather different meanings.
A “slut” is a woman who is promiscuous for fun. Specifically, I would identify a “slut” as a woman who exceeds a sexual partner count of 15-20 or so where it appears that she becomes incapable of a stable monogamous relationship. I find this boundary pops up again and again. For example, it is about the same as Terrence Popp’s “dick stacking test.” Popp says: take the number of sexual partners a woman has had, multiply by 6″ (the average dick length), and push her off a platform of that height. If she doesn’t get hurt, she’s OK. Obviously, 15-20 dicks would mean 7.5-10 feet, which is about as high a platform as a woman could be pushed from without injury.
But, even sex gets a little boring eventually. A woman becomes a “whore” when she stops having sex for personal enjoyment, and begins to see it as a means to some other end, typically money and status. Around this time, she stops having sex with sexy broke guys, and becomes a gold-digger. A “whore” may be paid by the hour; she may be paid in the form of presents, expensive dinners, weekends out of town or yacht voyages that affluent men often provide; or she may be paid by a multiyear contract (marriage), but in either case, its a sex-for-money transaction. Typically this transition from “slut” to “whore” takes place around age 26-28.
You could argue that any marriage can be a sort of sex-for-money transaction, but what characterizes the whore is that her benefit comes at another’s expense — her husband, children, and those around her. She is inherently destructive and consumptive. It is a negative-sum proposition. The man eventually realizes that he is married to a parasitic predator. A good wife works in cooperation with the husband, and the result is benefit for the husband and children, and also for the wife herself. It is inherently a productive, mutually-beneficial engagement.
Some whores go back to being sluts. If their attempts at gold-digging — or in fact marrying any beta chump who will serve as a meal ticket — fails, or if she blows up her marriage for an exit bonus of cash and prizes, she may go back to having sex for fun. This is typically between age 35-45. Then, she becomes a “cougar,” and goes back to sexy broke guys, typically much younger. She might still be conducting a gold-digging campaign of some sort, but without much success, having aged out of the range where any man with enough cash would be interested.
