You should. I find that's what separates the really great girls from the ho-hum ones. The great ones know how to keep things fresh and fun. Even a good one becomes a little dull when they just keep doing the same old same old. Others will start to give you the Wife Experience... they see you as a regular, so they go through the motions and nothing more. Probably the main reason I move on from a regular... no zip any more. She's still nice and someone else will think she's awesome, but for me, she's become stale cheese.
Like my ex wife. I imagine her new husband thinks she's great.
