Roissy has claimed that husbands who do more chores at home have sex less often because it is a turn-off to their wives.
The GSS asked respondents how often they have sex, and how many hours of houeswork they do in a typical week. Sex frequency is influenced a great deal by age, so I include it as a control:
Standardized OLS regression coefficients (sample size = 218, married men)
Hours of housework -.05
While age exerts a powerful effect on frequency of sexual intercourse, housework is unrelated. (It might have a small negative effect if the sample size were larger).
Wives are less likely to want sex if they are tired or if they are in a bad mood. They are more likely to be in a bad mood if they feel that their husband is not pulling his load. (I'm skeptical of the view that what a woman finds attractive in her man is his exploitation of her). The chance of her wanting sex will be higher if she gets manly vibes from her husband. So the best plan for a husband is to show his wife that he is doing his fair share, but to focus on manly types of work. That means work that is physical or technical. Much of it will be outside. If you don't know how to fix stuff, like a car--you're smart--learn. Avoid any type of work, except for barbecuing, that requires an apron.
The goal for a good marriage is to be traditional but to be just. In Bruce Charlton's words, be a patriarch.
