1 Corinthians 7:1-9 ESV
Now concerning the matters about which you wrote: “It is good for a man not to have sexual relations with a woman.” But because of the temptation to sexual immorality, each man should have his own wife and each woman her own husband. The husband should give to his wife her conjugal rights, and likewise the wife to her husband. For 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. Do 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.
Now as a concession, not a command, I say this. I wish that all were as I myself am. But each has his own gift from God, one of one kind and one of another.
To the unmarried and the widows I say that it is good for them to remain single, as I am. But if they cannot exercise self-control, they should marry. For it is better to marry than to burn with passion.
