It is a mystery for sure. My husband has a work from home job, and I'll admit that a majority of housework is done by him. BUT...even if I go way overboard and take care of that it doesn't work. You would think I would be the one who has lost interest in sex. I work 12 hour shifts 3 to 4 days / week sometimes more. But, I would be just so overjoyed if he took a little bit of interest in sex. He has none. It is a shame.
