Men who do more of the traditional stuff have more sex. Mowing the lawn is apparently sexier.
From the piece:
Husbands who do a lot of cooking, cleaning, laundry and other traditionally female forms of housework may do their marriages some good -- but, contrary to popular belief, they are not rewarded with more sex, a new study finds.
Instead, it's the guys who do the most lawn work, car repair, driving and bill-paying – traditional men's jobs – who have the most sex in marriage, the study suggests. The same is true for women who do the most traditional female housework, according to the study published in the February issue of American Sociological Review.
