There will always be imbalances where needs are not met, but to posit that most women use sex as a tool to manipulate men that are less than perfect doesn't sit

There will always be imbalances where needs are not met, but to posit that most women use sex as a tool to manipulate men that are less than perfect doesn't sit well with me. First, don't get so hung up on "perfect". I think the poster intended it to mean "passing some standard", presumably a high one, and possibly one they themselves are unable to meet. Their word choice just wasn't very good. As for the rest, it doesn't have to sit well with you: it's simply the way things have been in any culture where we expect long-term relationships and especially any culture where you have heredity concerns. Consider the stigma around, for example, "being a slut"--a great deal (if not the majority) of which is perpetuated by women against other women, from mothers warning their daughters, and so on! The entire mythos surrounding virginity and monogamous relationships and whatnot hinges on the notion that women control the supply of sex, that men voluntarily prostrate themselves to obtain that sex, that men punish other men who take it by force (because, frankly, women are ill-equipped by mother nature to do so), that men need to know that their children (historically and especially the eldest male) are in fact theirs (something hard before paternity tests and so a piece of the slut-shaming puzzle), and so on. To deny that women are at least somewhat shrewd and discerning in their sexual exploits is patronizing.
