Men with no interest in sex or women are now so common in Japan that they have a name: herbivorous.
A third of teenage boys in Japan (age 16 - 19, not the young ones), say they have no interest in sex. Some of them say they despise sex.
One possible cause: most teenage girls in Japan (59%) say the same thing.
40% of married couples report that they have not had sex in the past month.
The Japanese fertility rate is 1.37, way below the 2.1 children per fertile woman necessary to replace the existing population.
The idea that large fractions of young men would have no interest in sex is hard to grasp.
No one knows why.
