Proverbs, addressed to young men approaching the age of marriage, takes a different view. It holds up marriage as a crucial choice, to be made with great care. Therefore, her character matters far more than her physical beauty. Not that Proverbs ignores the physical side of love. It warns young people against sexual sin precisely because this wastes sexuality on unsatisfying, unloving relationships.
Sex ought to be saved for the long-lasting, productive joy of marriage.
