Just curious, and don't take this the wrong way, because I do agree with some of what you're say here....but what is your definition of a "male slut"? Do they even exist in your world?
Male sluts exist, and they're called gigolos, but they don't have as much of a market as the call girls do
The true flip side of the slut is the sugar daddy. He's the guy the cute girl keeps around because he buys nice stuff and pays the bills. She tolerates him only because of what he provides, rather than liking him for who he is. She might even pretend to like him or love him, but it is as much an act as that of the "player" guy who tells his current bed-partner what she wants to hear.
In neither case is the slut or the sugar-daddy loved for what they are, only used for what they provide. In both cases there's a similar level of anger the first time they realize they are only being used by people who personally hold them in contempt. Some eventually resign themselves to taking what they can get.
