Ants

Evolving into humanised things, Ants have become surprisingly inclusive, creating a naked society and letting humans wear the chitin of Ants. Also, males are a protected resource; they cut down the excessive population and use a small population of males to whore out to the various colonies, allowing great workers to become mothers and replenishing the human population. They are kept around for their sex potential, used to keep the queens reproducing eternally till they pass and maintain genetic diversity alongside the male drones who go out to properly diversify Ant genes.
