You knew we'd have to get to this eventually. Two recent items, and the fact that this is the ultimate topic for both men and women to talk about during Father's Day Week, propelled me to (excuse the expression) do it now:

--If you didn't catch the piece on two married couples who had sex every day for an extended period, you'll want to read it now. The story doesn't mention whether these couples have children, which, as we all know, adds an extra wrinkle...

--Meawhile The Poop, the San Francisco Chronicle's "baby blog," has a post on fitting in sex when you have kids that talks about the challenges of doing the deed when you're cosleeping with a young child. Another one we can talk about: what to do when you have a small house and a pre-teenager who doesn't fall asleep until 11 p.m. -- later than you do.

And where do we stand on "date nights" -- scheduled appointments for sex -- versus spontaneity? How often should "date nights" occur?

Post below -- but keep your comments G-rated, please.
