1 Corinthians 7:1-5

Now regarding the questions you asked in your letter. Yes, it is good to abstain from sexual relations. But because there is so much sexual immorality, each man should have his own wife, and each woman should have her own husband. The husband should fulfill his wife’s sexual needs, and the wife should fulfill her husband’s needs. The wife gives authority over her body to her husband, and the husband gives authority over his body to his wife. Do not deprive each other of sexual relations, unless you both agree to refrain from sexual intimacy for a limited time so you can give yourselves more completely to prayer. Afterward, you should come together again so that Satan won’t be able to tempt you because of your lack of self-control.
