"Adults are having sex less often than they were 20 years ago, according a US study based on a survey of almost 27,000 individuals.

Researchers have found that adults, on average, were having sex seven fewer times annually in the early 2010s compared to the early 1990s, and nine fewer times compared to the late 1990s.

The study follows research published by the same team last year which found that the percentage of adults aged between 20 and 24 who had had no sexual partner after the age of 18 had more than doubled between those born in the 1960s and the 1990s, rising from 6% to 15%."
