The thing many Mangakas and even writters ignore is that when you use this theme of reversal gender social dynamic or "a world were women chase the men" you have to be thorough, you almost have to re-writte human history or keep it obscure, the variables are too many, for example who would be the dominant gender? males are still stronger physically, and more competitive, other mangakas resolve this by giving females a magically superior strength, (wich is dumb) but it makes sense since that is how we see the world and by simply changing gender roles authors create this kind of story.
And this is the root of all the issue, they just want a quick setting to develop this fantasy of being dessired by women, to be showered with attention, to have a women chasing you by simple being a man, or a submisive fetish. Authors dont care about the implications, plenty of mangas use this trope to milk this fantasy and get viewers, all through the lens of current japanese social condition. (Do it with a mexican MC and this would be a whole different story).
But my point is that None of them bother to worldbuild their premises right because they want to milk the fantasy not to properly write this complex and very interesting idea, and that is a sin for any creative author.
