How can a wife be convinced of matters of sex and love?

Each spouse has rights and duties. Among the most emphasized rights of a husband upon his wife is her obedience to him in what is good, especially if he calls her to bed. If she refuses, the angels curse her until morning, and she is considered rebellious and disobedient to Allah Almighty. If there is no love from your wife, but she does not disobey your command and does not neglect any of your obligatory rights, then she is not to be blamed for that.
