The number of American adults reporting that they have not had sex in the past year hit a record high in 2018, data shows.

The Washington Post analyzed the latest data from the General Social Survey and found that 23 percent of adults, or nearly 1 in 4, said they had not had sex in the past year. A large number of them were “20-something men,” the newspaper reported.

The analysis found that since 2008, the percentage of men under 30 reporting no sex had nearly tripled to 28 percent, compared with an 8 percent increase reported by women in the same age bracket. It found that 18 percent of women between the ages of 18 and 30 reported no sex in the past year.

“There are more people in their twenties who don’t have a live-in partner,” Jean Twenge, a professor of psychology at San Diego State University, explained to the Post. “So under those circumstances, I think less sex is going to happen."

Twenge pointed out that the difference between the number of 20-something men and women reporting sexlessness could be attributed to a decline in the number of young men in the labor force. The survey showed that 54 percent of unemployed Americans did not have a steady relationship versus 32 percent of employed Americans.

The finding that young men are more likely to live with their parents than young women is also a factor, Twenge said. "When you're living at home it's probably harder to bring sexual partners into your bedroom."
