Couples who have sex just once a week are the happiest

THE SECRET to marital bliss is not very sexy, researchers announced Wednesday.

Couples having sex every day are not necessarily happier, a new study published by the Society for Personality and Social Psychology reveals.

Those doing the deed once a week are just as cheery, researchers said.

“Although more frequent sex is associated with greater happiness, this link was no longer significant at a frequency of more than once a week,” lead researcher Amy Muise said.

“Our findings suggest that it’s important to maintain an intimate connection with your partner, but you don’t need to have sex every day as long as you’re maintaining that connection.”

Couples shouldn’t put “too much pressure on engaging in sex as frequently as possible,” she suggested.

The study was based on data collected over four decades from a survey of 30,000 Americans in relationships.

“Our findings were consistent for men and women, younger and older people, and couples who had been married for a few years or decades,” Muise said.

But there was no association between sexual frequency and happiness for singles, noted Muise, a social psychologist at the University of Toronto-Mississauga.
