There's no question that even in my own marriage that concern about pregnancy was a real one. And you know there were times when my wife and I wanted to have sex and I'd say, 'you know, you got to go get the diaphragm' and she said, 'oh I'm so tired'. She was working, I was working. And that's how mistakes occurred. The diaphragm doesn't work very well when it's in the medicine cabinet. It just doesn't work there.
