I Corinthians 7:3-7

³The husband must fulfill his duty to his wife, and likewise also the wife to her husband. ⁴The wife does not have authority over her own body, but the husband does; and likewise also the husband does not have authority over his own body, but the wife does. ⁵Stop depriving one another, except by agreement for a time, so that you may devote yourselves to prayer, and come together again so that Satan will not tempt you because of your lack of self-control. ⁶But this I say by way of concession, not of command. ⁷Yet I wish that all men were even as I myself am. However, each man has his own gift from God, one in this manner, and another in that.
