A man will teach his wife what is needed to arouse his desires. And there is no reason for a woman to know any more than what her husband is prepared to teach her. If she gets married knowing far too much about what she wants and doesn't want then she will be ready to find fault with her husband.
A marriage based on full confidence, based on complete and unqualified frankness on both sides; they are not keeping anything back; there's no deception underneath it all. If I might so put it, it's an agreement for the mutual forgiveness of sin.
It's like going to the courthouse and picking out 50 marriage certificates and spreading them out and saying who is going to be married 40 years from now. There are so many factors that come into play. How is a player going to mature? Is he going to have a drug problem in a couple of years? There are so many ways for a kid to go sideways, and sometimes it has nothing to do with anything negative.
