The RT article said that "Nearly half the couples had not had sex in a month". That happens because they prefer to do something else instead.

Will you grant that this means that interest in sex has fallen?

The Politifact article says "In 2013 a whopping 45 percent of women aged 16 to 24 ‘were not interested in or despised sexual contact,’ and more than a quarter of men felt the same way."

Which matches my claim:

> Nearly half of young women in Japan are "uninterested in sex" or "averse to sex"

My claim was that disgust with sex is rising.

Another article makes these delightful claims:

  - More than 40% of Japanese 18- to 34-year-old singles claim they are virgins.
  - the fraction of people getting it on at least once a week fell from 45% in 2000 to 36% in 2016.
  - more than twice as many millennials were sexually inactive in their early 20s than the prior generation was.
  - In 2016, 4% fewer condoms were sold than the year before, and they fell a further 3% in 2017.
  - Teen sex is flat and has been on a downward trend since 1985
  - The median age for first marriage in America is now 29 for men and 27 for women, up from 27 and 25 in 1999.
  - the highest drop in sexual frequency has been among married people with higher levels of education
  - those with offspring in the 6 to 17 age range were doing less of what made them parents

What do you make of these data points? I think they successfully demonstrate that interest in sex is falling.
