How often do you?
I told my DH after my second child that we would once a week. I have tried to stick to that but things get in the way: children, aunt flo, being tired etc.
He keeps track of the schedule and I agreed to it so I need to stick to it and oh by the way two in one week does not get you out of the next week.
Do you have a schedule.
Oh wait it is Monday I have to go and wake him up.
