I don't know what information you've seen about women with multiple sex partners but I've read that, for both women and men, the odds of a successful domestic relationship go down with the number of prior partners you've had.

I have to wonder, though, if one nighters or transactional sex is as impactful on that ratio. Who knows? It seems to me it would be the multiplicity of failed romantic relationships that would be more detrimental to psychological health than just casually banging a bunch of folks or turning a lot of tricks.
