Note to you men out there: Stick with manly chores like mowing the lawn, washing the car and blowing the leaves, and let the women-folk handle the cooking and cleaning — that is, if you want to get her in the sack tonight.These are the conclusions of a University of Washington study — published in the February issue of the American Sociological Review — which suggests that men who do housework generally associated with June Cleaver are less likely to have sex with their wives.”Results show that both husbands and wives in couples with more traditional housework arrangements report higher sexual frequency, suggesting the importance of gender display rather than marital exchange for sex between heterosexual married partners,” said authors Sabino Kornich, Julie Brines, and Katrina Leupp.Atta boy!According to the study, based largely on surveys of 4,500 straight, married couples (no gay marrieds were involved here) from 1992-1994, when the husband and wife stuck to their traditional roles, couples had more sex than couples in which the man did all women’s work.On average, couples spent 34 hours on traditional female household chores, like cooking, cleaning, shopping and sewing, and another 17 hours doing men’s tasks, which include stuff like fixing the overflowing toilet and pruning the trees. Men spent did about one-fifth of the female tasks, and only a little more than half of the male tasks. This suggested that women did more housework overall.Men and women reported on average having sex five times the month before the survey was taken. In households where the women did all the female chores, they had sex 1.6 times more a month than the households where the men did all the traditionally female tasks. Households where men did 40 percent of the housework had one less sexual event on average.
