Still, I wanted to draw attention to the fact that most people are looking for some mix of physical intimacy (sex) and emotional intimacy (companionship).
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.
transfire explicitly was addressing the condition of men seeking sex, which is not the same as mean seeking "companionship - for someone they can count on for support and non-judgement during times of crisis, but who will also push them to become better and achieve their goals".
Insofar as women are seeking that (whether or not that's like you), that would likely be a problem for men who are simply seeking sex and not to find or provide companionship.
To the extent that there are asymmetries in the degrees to which (heterosexual, for simplicity) men and women seek sex vs. mutual companionship in relationships, this will produce advantages and disadvantages to some people on both sides. For instance, to the extent the stereotypical idea that men are more prone to seek sex and women more prone to seek companionship is true (note that I'm not claiming it is), men who seek sex will have a more difficult time, as will women who seek mutual companionship (while, conversely, women who seek sex and men who seek mutual companionship will have a comparatively easy time.)
Its a simple issue of poor alignment of supply and demand (but it doesn't make it worse to be a man than a woman -- it makes it worse to be a man or woman seeking what people of your gender are most prone to seek, and people of your preferred gender are least prone to want to provide.)
