A survey earlier this year by the Japan Family Planning Association (JFPA) found that 45% of women aged 16-24 “were not interested in or despised sexual contact”. More than a quarter of men felt the same way.
Some years ago I spent three months in Japan. I went the length of the main island and visited and stayed with 23 different families as well as staying with two religious communities.
I had no affiliation with the religious communities and was invited (as with the other families) simply on the basis of increasing cross-cultural awareness.
I really should write about it sometime, before it fades from memory.
