Some 15% of adults aged 20 to 24 reported having no sex since turning 18, compared with just 6% of the previous generation at that age, the study found.

Previous research has also found that millennials — born from the 1980s to 2000 — have fewer sexual partners than Generation X’ers or baby boomers, Dr Twenge said.

And older men (16 per cent of 50-64 year olds) are more likely to use them than older women (3 per cent.) “I think it’s great that 3 per cent of older women are using these sites for sexual hook-ups,” says Emily Power Smith, a sexologist.

The only generation that showed a higher rate of sexual inactivity in the analysis was born in the 1920s.

To look at generational shifts in sexual activity, researchers examined survey data from a nationally representative sample of more than 26,000 adults.
