The young knight must prove himself in battle to win the favour of the fair maiden. What must the fair maiden do? Nothing. She just sits there and passes judgment on the young knight.
I many fairy tales, such as The Beauty and the Beast, young men compete for the female's approval. She sits in judgment of the men. No one judges her and no one questions her judgment of the men. If either man fails to please her, that man is considered to be in the wrong and even a bad man, just because he did not please her.
I believe that some men have a form of mental illness where they accept such a paradigm for their lives, because this is what they have been taught. They believe that the only purpose of a man is to please women. These men are very chivalrous. They spend much time working out in the gym, they fully support women-only shelters and think it exciting to lay their coat over a mud puddle for a woman.
Also, they must have as many girlfriends as possible to prove to themselves that they are pleasing women. They then become the classic cheating husband. They didn't mean to hurt their wives, but they seem to be driven to please as many women as possible, so that they can feel self worth and prove that they are 'real men'.
