1 Corinthians 7:1-5

Now with regard to the issues you wrote about: “It is good for a man not to have sexual relations with a woman.” But because of immoralities, each man should have relations with his own wife and each woman with her own husband. A husband should give to his wife her sexual rights, and likewise a wife to her husband. It is not the wife who has the rights to her own body, but the husband. In the same way, it is not the husband who has the rights to his own body, but the wife. Do not deprive each other, except by mutual agreement for a specified time, so that you may devote yourselves to prayer. Then resume your relationship, so that Satan may not tempt you because of your lack of self-control.
