“Not buying this. Human nature being what it is.”
Well, start buying it. More and more studies are showing this. Young people are still interested in sex. They just aren’t interested in PEOPLE. Japanese scholars have been seeing this unfolding in Japan for years. Plenty of pornography, but less and less actual sex. This is from 5 years ago already: https://www.theguardian.com/world/2013/oct/20/young-people-japan-stopped-having-sex
Still not convinced? How about this: “Nearly a third of Japanese people are entering their 30s without any sexual experience, leaving the country facing a steep population decline” https://www.independent.co.uk/news/world/asia/japan-sex-problem-demographic-time-bomb-birth-rates-sex-robots-fertility-crisis-virgins-romance-porn-a7831041.html
More proof - the Incel Movement: https://www.nationalreview.com/2018/05/sex-is-god-for-incel-sexless/
I’m telling you, it’s happening.
People tell pollsters & surveys a lot of things, and often they don’t tell the truth, or the whole truth. The last election being such a case. Women are notorious for not telling the truth about their sexual lives.
