British people are having less sex now than in recent years, according to a large national survey.
The findings, published in the British Medical Journal, suggest nearly a third of men and women have not had sex in the past month.
That’s up from around a quarter in 2001, according to the data from 34,000 people.
Less than half of men and women aged 16 to 44 have sex at least once a week, responses show.
Over-25s and couples who are married or living together account for the biggest falls in sexual activity across the 21-year period.
The data the researchers looked at came from three successive waves of the British National Survey of Sexual Attitudes and Lifestyles carried out in 1991, 2001, and 2012.
