Researchers from Carnegie Mellon University in Pennsylvania have found that couples who have more sex are not necessarily happier.
They also found the results from their study could help people improve their sex lives.
Scientists studied 128 married couples aged between 35 and 65. They asked half of them to double the amount of sex they had each week for three months. The other half they instructed to carry on as usual.
Couples who doubled the amount actually reported they wanted less sex, and the feeling of requirement to have more sex actually ruined the enjoyment.
The lead author of the study said they would conduct the research differently next time to make the couples feel less pressure to have sex.
But they claim the study could help couples improve their sex lives, saying that instead of focusing on the amount of sex, they should 'create an environment that sparks their desire and makes the sex they do have more fun'.
