When you think of a deliriously happy couple, you might assume they’re having sex every waking moment. But according to a new study, it turns out that many satisfied couples spend most nights reading in their pajamas instead.

Researchers at the University of Toronto collected data from surveys of 30,000 Americans over the past 40 years to see if happy couples have more or less sex than unhappy ones. Their results, published in the journal Social Psychological and
Personality Science, revealed there’s a sweet spot for happy couples everywhere, and that’s having sex once a week.

They found that more sex meant more happiness, but there was a limit to the connection, and that was the once a week mark.
This was the case regardless of age, gender, or length of a relationship. But this was only for people in relationships; for
single people, there was no link between frequency of sex and general happiness.

Why does satisfaction drop off after once a week? It remains unclear, but the study authors write that couples might feel
satisfied if they’re having the amount of sex they think is “average” for couples like them. Previous studies have found that
people tend to report they have sex approximately, yup, once a week, so couples who do it that often probably feel pretty good
about themselves.

Overall, the researchers say their results shouldn’t be a prescription for more or less sex, but a reason to have a conversation
with your partner and see if you’re meeting each other’s needs in the bedroom.

“Our findings suggest that it’s important to maintain an intimate connection with your partner, but you don’t need to have sex
everyday as long as you’re maintaining that connection,” researcher Amy Muise said in a statement. “It’s important to maintain
an intimate connection with your partner without putting too much pressure on engaging in sex as frequently as possible.”
