@Pixi97 100% agreed. It's also VERY important to have people like yourself remind everyone that none of this realistic. In the real world, girls are the same as guys. We're all sweating, pooping primates whom hit the evolutionary jackpot. A lot of what makes a "cute girl" is a social construct that we collectively nudge 51% of this primate population towards embodying. Given we're all the same where it matters, really, is why I wish people wouldn't get themselves so tied up in knots about interacting with the opposite sex.
I tend to think of anime/manga people as existing in realities parallel to, but not the same as us. They're almost more like angels than ape, unless they're deliberately drawn otherwise. In anime/manga the gender gap is much more defined and dramatic. While I just said we're all the same in reality, I don't think that's quite as true of anime/manga people. So it makes sense to me that an anime-verse like Fukuoka Taro's could exist, where every guy in it secretly yearns to be a cute girl.
(by the same token, I could imagine the reverse premise too. A niche BL/yaoi shoujo manga where every schoolgirl is a hot bishounen waiting to happen. I've seen at least one artist on Pixiv who is all about that exact very thing, actually.)
But yeah, thank you very much for the reality check. It is important, especially if you're indulging in works like Fukuoka Taro's. I'm still enjoying this fantasy all the same.
