God, woman, what is your problem?
Your husband just wants what he wants.
He's being very clear and I think you should just do it. Clearly, by resisting, you've somehow driven him to get involved in child porn.
But seriously, the whole situation does raise some questions for me. Like, Did this just come up? You've been married for nine years. And, did you decide to go with the paper option for tracking your GBDs, or go for the modern-day computer mode? I totally would have gone for the computer. It's so much easier to just, like, put a little flag on your calendar to track them. Or something.
