1 Corinthians 7:2-6

2But because of the temptation to sexual immorality, each man should have his own wife and each woman her own husband.

3The husband should give to his wife her conjugal rights, and likewise the wife to her husband.

4For the wife does not have authority over her own body, but the husband does. Likewise the husband does not have authority over his own body, but the wife does.

5Do not deprive one another, except perhaps by agreement for a limited time, that you may devote yourselves to prayer; but then come together again, so that Satan may not tempt you because of your lack of self-control.

6Now as a concession, not a command, I say this.
