I'm not going to look these up, but supposedly polls were taken, and there are statistics to prove it. My friends were telling me about this on Tuesday. I realize that correlation does not equal causation, sample size, blah blah, blah, so these "facts" are probably B.S., but I wanted to see if they hold true for you. Oh, also, I disagree with the whole premise of "male" chores and "female" chores, and I just think that husbands and wives should do what they like, what they're good at, and what they have time to do, and that's different for different couples, but I do think the responsibilities should be split somewhat evenly.
Anyway, enough setup - these are two independent studies, and the results are:
1. Couples where the household chores are more evenly split (like the same amount of work for both, although it could be different jobs) are more adventurous and experimental in the bedroom than couples where one person does all the household chores.
2. Couples where the woman does the more traditionally "female" chores like washing dishes and the man does the "male" chores like cutting the grass have more sex than couples who deviate from these gender stereotypes.
I personally think that #1 could be true, but #2 is probably not. I have no idea whether the study for #2 said anything about same-sex couples, but the premise is that if a woman does the "womanly" chores, it will make her feel more feminine, and if the man does the "manly" chores, he'll feel more masculine, and somehow that = more sex. I know that DH is more likely to get sex when he does something like empty the dishwasher or soothe DS back to sleep, so that's anecdotal "proof" against that theory.
