(Particularly of a submissive and/or agreeable temperament).

Why?

There's this idea that young, hot women are at a huge advantage in dating compared to every other demographic. The only advantage this demographic have is broader sexual opportunities.

I see it time and time again, young, hot women often get messed around and left on the shelf (unmarried) longer than their less attractive and older counterparts because they have too many men swarming them for their body. Add in submission and agreeableness, chances they're going to end up with the wrong person because they will say yes to one of the guys swarming her, who is only pretending to be nice or interested in the same things as her due to wanting her body.

Uglier and older women tend to have an easier time finding "the one" and love in general because the people surronding them are more likely around because they're genuinely interested in them, as a person, not a prize to seize.

Manospherian types obsessed over this particular age group but tend to miss all the disadvantage, don't seem to see this and hyperfocus on all their slips up. They fetishize the looks and submissiveness of this group when those very attributes are what hold them back from securing a long term, compatible partner.
