In that survey, 65.8 percent of women 16-19 were not interested in sex or felt an aversion to it, and 39.2 percent of women 20-24 felt the same way.
This survey is the only one we could find that asks about specific views of sex.
Endo mentioned another survey by the government, the National Institute of Population and Social Security Research, that asked 4,276 women, of which about 3,400 were 18 to 34, if they had ever had any kind of sexual encounter.
The percentage of women ages 18-19 who said they had never had sex was 68.1 percent; for women 20-24, it was 40.1 percent; for women 25-29, it was 29.3 percent; and for women 30-34, 23.8 percent.
