Coming back for seconds

SOH has a post today about her husband wanting more sex. Um. Just a comment. If you do anything too much it becomes routine, a chore, and no longer very fun. So, I would suggest that incorporating porn into sex every day might be a bad idea. I'm game for the occasional semi-normal pornographic film, but if we watch it too much we both start criticizing the actors' technique rather than getting to our own good stuff. Your thoughts, experiences? Curious.
