I must echo Lovemyshiba's comments..I don't think it is a gender thing. Here is the reverse..my friend at work- married with two kids-has NEVER cut her grass. She doesn't know how to run a lawnmower! When one goes from one's parent's house to one's spouse's house...some things just get overlooked.

I would leave his laundry aside...let him learn how to do it. What happens if you aren't there to do it? Say, attending a PT meeting or something? He he he...
