Pretty sure there are josei with this exact setup, but your point is still a good one. It's mindboggling how
menpeople treat promiscuous men (Chad!) differently from promiscuous women (used goods!) when there's no logical reason to do so.
To add two to the list I
think haven't been mentioned yet:

and

For the former: No romance yet (aside from some blushing young men in the periphery), although I personally find the heroine to be a bit insufferable and male wish fulfillment-y by being the perfect MILF waifu. It's kinda nice to see her presented as a mother without the need for a man, though.
(yeah yeah, I get it that by being such a doting mother she's enforcing gendered stereotypes. Baby steps)
For the latter: It's all about the kaiju (and a badass FMC wih an axe). Tiny bit of "romance" that quickly gets subsumed by said kaiju.
