I'm looking for a manga or story about a guy in a world were men act like women and women like men.

But he's not from that world and acts normal, which Is basically a tomboy in that world.

I really find stories that flip socialite norms upside down to be hilarious

The World of Moral Reversal

The original hentai is about a guy going into the world, meanwhile the newer series is about a girl suffering through it (With the original hentai protag showing up later on).

I think Witch Craft works might fit the bill but the male mc not in another world
