Do Traditional Husband Chores Lead to More Frequent Intimacy?

I just came across a story about a controversial study that was featured on NBC’s Today Show.

Here is an excerpt:

Heterosexual married men who spend their time doing yard work, paying bills and changing the oil have more sex than husbands who spend their time cooking, cleaning and shopping, according to a new study on the subject of housework and sex.

From the study:

“Households with a more traditional gender division of labor report higher sexual frequency than households with less traditional gender divisions of labor,” says Sabino Kornrich, lead author of a study that appears in the February issue of the American Sociological Review. “Housework is something that people use as a very important way to express gender, masculinity and femininity. We weren’t surprised to think that sex might be more tied to this type of gender expression.”

In conclusion:

“For couples in which men did no ‘core’ housework [chores that are typically identified with women], sexual frequency was 4.8 times per month,” says Kornrich. “For couples in which men did all of the ‘core’ housework, sexual frequency was 3.2 times per month.”

Thoughts? Reaction?
