‘... A couple who are considerate of each other and who are faithful to their marital obligations will never be interested in another man or woman. Satan easily recognizes when the couple does not fulfill their responsibilities to each other. So he offers an affair opportunity to satisfy the body's normal needs. The couple who use sex as a tool for fighting rather than as a tool to build a family is like asking Satan to destroy the family.’
