After about a week, I start getting on DH's case in a playful, "get upstairs now!" kind of way. But if he wasnt around, I could go indefinitely. I wouldn't take it upon myself to do something about it.
The longest I have gone for is 3 months.
Quoting Anonymous:Indefinitely. It's been over a year so far and I'm not really missing it. I could go the rest of my life and be perfectly content.
