How much sex is enough? It’s not uncommon for couples to worry they’re falling short of a mythical standard for how much sex they should be having. Despite the belief that more is always better, though, a new study has a surprising conclusion about how many times a week happy couples have sex: just once.
A survey of 30,000 U.S. adults over four decades concluded that sex once a week is the optimum regularity— and more frequent sex won’t actually make a difference, reports The Society of Personality and Social Psychology.
