They're all just like you and I user

We don't talk about the fourth hole.

One (1) vagina, collectively.

Well, it worked with eye, why not a cunt

This sounds like something straight from Oglaf

Due to their ability to carry children, they are considered crucibles of the soul and so are more likely targeted by demons and spirits to be corrupted. This also results in women being more magically adept than men.

This sounds pretty cool or REALLY magical realm depending on what you mean by "corrupted"

And men thus more liked by the "sterile" Gods?

Th grils are cute. Some of them go on adventures, and some are NPCs.

Female merfolk are mermaids; males are men with gills.

You don't understand. They're symlinked. When you fuck one vagina you fuck them all.
