A new study has revealed that stress and tiredness caused by recession, combined with boring sex, has put a dampener on everyone's love lives.
According to the research, more than a quarter of people surveyed said they were making love less than they were a year ago, with women citing tiredness and men blaming their lack of libido on money worries.
Researchers Linda Kelsey said that for many people working longer hours and juggling jobs and childcare, sex was no longer a priority.
The survey of more than 1,000 people, commissioned by Good Housekeeping magazine, showed that couples aged 35 to 64 were the most likely to have had less sex this year than last.
A quarter of men surveyed said their partner had lost interest in the past year, compared to 15 percent of women.
However, 91 percent of men and 92 percent of women surveyed were still attracted to their partner, suggesting that reduction in sexual activity is linked to outside pressures.
Relate counsellor Paula Hall said it was not surprising that financial worries were the main cause of men's lack of interest in sex.
"When we are stressed our bodies produced stress hormones which can affect libido very negatively," hall said.
"Men have up to 40 times more testosterone than women, which gives them a much more urgent sex drive which carries them through physical tiredness," she said.
Hall also said there were several reasons why women were twice as likely as men to be too tired for sex.
"It doesn't necessarily mean that women are more tired than men, but environmental factors like tiredness and mood have more effect on women's sex drive.
"Men have up to 40 times more testosterone than women, which gives them a much more urgent sex drive which carries them through physical tiredness.
"Women do also tend to get less sleep than men," she added.
