Domestic sexual decline is quite evident.

According to a sex life survey conducted by an institution, among men and women aged 45 and above, those who have no sex at least once per month or have had no sex at all within a year account for 40%. In the 45 to 35 age group, sexless marriages are also at around 20%.
Young people are also showing a trend toward sexual decline.
Among those born from 1995 to 1999, 20% of men have had casual sex hook-up experiences, 17% of women have. For the cohort born from 2000 to 2005, the male hook-up rate is only 8%, and the female rate is 4%.
The institution believes that the economy is the main reason behind sexual decline. They found that even if people work 996, they can still maintain sex once a week, but if people become unemployed—even if they do not need to work at that time—they instead can’t maintain sex once a week anymore.
