Herbivore men and national gender imbalance

There's a growing phenomenon in Japan. A large fraction of Japanese men have no interest in sex. I wouldn't care to speculate why right now, but there's one particular consequence I'm interested in: there are a lot of Japanese women who will never have a husband.

Other countries, notably China and India, have more men than women due to selective abortions. That's a lot of men who will never have a wife.


Japan and China don't get along well for... historical reasons. But Japan and India seem to do fine. Maybe we should hook them up?

That would be an interesting world.
