God created women specifically to keep men in good shape.

After all, if people were an androgynous species, then they would be an inert species, stagnating in development.

It is sexual desire and sexual selection that is the main source of the development of society.

It is the dynamics, when men are consumables, and women are strategic resources, that is the engine of progress.

Men strive to achieve something and sacrifice themselves in order to attract a woman. A man seeks to gain power so that he can access more women and spread his genes

This is a primitive, but very working scheme. I don't know what could be better in nature. Hermaphodite species are often ringworms and hydras.
