Jean-Jacques Rousseau said this quote

The decent man and the lover holds back even when he could obtain what he wishes. To win this silent consent is to make use of all the violence permitted in love. To read it in the eyes, to see it in the ways in spite of the mouth's denial, that is the art of he who knows how to love. If he then completes his happiness, he is not brutal, he is decent. He does not insult chasteness; he respects it; he serves it.
