A couple of our favorite daddy writers have been discussing the newly coined word, choreplay. This refers to a man's ability to get his partner in the mood by stepping up his involvement in housework or childcare. Kind of a cute phrase, with more than a bit of truth to it. The word was created in a Parenting magazine article and discussed here.
Some of the reasons given for the effect of choreplay are that women are less tired if their husbands/lovers are picking more slack, and that women find a man unloading the dishwasher to be sexy because he's 'fighting for her love'. Okay, I'll buy these reasons (although they maintain the assumption that housework and childcare are primarily a woman's responsibility). But I would add that choreplay mainly works because men look really sexy when they are competent at housework and childraising. If your guy is loading the dishwasher with stuff that says 'not dishwasher safe' or so awkwardly playing with the kids that he's boring them to tears, I doubt this would be very attractive.
Competence in any aspect of one's life is sexy. It works on the job, in sports and in the bedroom. It certainly works in the kitchen. This is one of the many reasons why men might want to roll up their sleeves and get busy learning how to do stuff around the house, and give up the ol' pretend-we-don't-know-how tactic to avoid the chores.
