My views of Japan's sexuality mostly align with those in that article. It talks about the recent trend of many Japanese not having sex (I claim that historically, most humans in general do have sex); furthermore, it claims a likely significant cause is the extreme pressures needed to maintain social status. It does quote a man citing similar trends in Britain; strange again, considering that at least as of 2014, studies show Britain having about a 4% virginity rate. Japan seems to be an outlier whose culture is resulting in a collapse of sexuality. Can you extrapolate evolutionary selection pressures from this?
