my theory on why men have sex at ALL after a certain number of years being married to the same woman

Just curious, around what year would the "cut off" date be?

[Treebeard]

I think there's an old and very bad rhyme that predicts that accurately, "when she comes in to take a s**t while you are in the shower."

Just curious, around what year would the "cut off" date be?

Well, after the last child your wife wants is born, she starts giving little clues that sex isn't numero uno on the list anymore. Little things like, "I have to be back downstairs in fifteen minutes," using the remote control during sex, and questions like, "are you almost done?" tend to make guys a little less enthusiastic. After age forty, guys equipment gets a little less reliable, and the second time you hear, "I don't have time for this", your hard-on is pretty soft-boiled.
