Have you and Grant talked about him getting a Vas? Its out patient, its easily reversible and the healing time is like NOTHING compared to what a woman goes through getting her tubes tied.

I know thats a big step for him, but so is the risk of you getting pregnant right now too.

Honestly, you should just tell the man to stop being so damn sexy and a wonderful husband, then MAYBE you could resist him a little better? :P
