>What's the old saying? A newly-married couple puts a marble in a jar every time they have sex during their first year of marriage. Then remove one marble every time, beginning year 2 and beyond. They never empty the jar. That certainly doesn't line up with my experience, or the stats I've read. From what I've heard, it's pretty common for married couples to keep at it (with a slow decline, as both parties age) until they physically can't any more. And with modern technology (cialis etc.), that age keeps getting pushed further and further up.
