Couples who establish a traditional division of household chores have more sex than those who distribute all household chores equally, according to the University of Washington (USA).
The authors assure that when women make food, clean the house and do the shopping, while men maintain the garden, clean and check the mechanics of the car, and are in charge of the electrical and plumbing tasks, the frequency with which they have sex is higher.
Specifically, while on average the couples studied had sex five times a month, the figure practically doubled when the husband did not cook, wash, or dust the house. "The results show that gender still conditions the daily life of a married couple," concludes Julie Brines in an article published in the American Sociological Review . The study is based on data from 4,5000 American heterosexual couples collected between 1992 and 1994 , so it would be necessary to analyze whether this trend in the division of domestic tasks – in which, for example, childcare did not appear – has changed in the last two decades.
