Many men, even Christian men, view sexual relations with their wives as little more than an opportunity to masturbate. They are concerned only with pleasing themselves. They do not realize that God gave them their sexual organs, not primarily for their own pleasure, but rather for the pleasure of their wives (1 Cor. 7:4). They have never learned that in sexual relations, as in all other areas of life, it is more blessed to give than to receive (Acts 20:35).
