"If that isn’t exciting enough, try this: Couples who share chores equally have more sex. As the researchers Constance T. Gager and Scott T. Yabiku put it, men and women who work hard play hard. One of us, Sheryl, has advised men that if they want to do something nice for their partners, instead of buying flowers, they should do laundry. A man who heard this was asked by his wife one night to do a load of laundry. He picked up the basket and asked hopefully, “Is this Lean In laundry?” Choreplay is real."
The claim that they have more sex has a link to a study.
