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 woman should say: "Have I made him happy? Is he satisfied? Does he love me more than he loved me before? Is he likely to go to bed with another woman?" If he does, then it's the wife's fault because she is not trying to make him happy.
Every man has been brought up with the idea that decent women don't pop in and out of bed; he has always been told by his mother that "nice girls don't." He finds, of course, when he gets older that this may be untrue-but only in a certain section of society.
A woman asking "Am I good? Am I satisfied?" is extremely selfish. The less women fuss about themselves, the less they talk to other women, the more they try to please their husbands, the happier the marriage is going to be.
