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.
I say this as a concession, not as a command.
But I wish everyone were single, just as I am. Yet each person has a special gift from God, of one kind or another.
So I say to those who aren’t married and to widows—it’s better to stay unmarried, just as I am.
But if they can’t control themselves, they should go ahead and marry. It’s better to marry than to burn with lust.
But for those who are married, I have a command that comes not from me, but from the Lord. A wife must not leave her husband.
References for 1 Corinthians 7:10
But if she does leave him, let her remain single or else be reconciled to him. And the husband must not leave his wife.
Now, I will speak to the rest of you, though I do not have a direct command from the Lord. If a fellow believer has a wife who is not a believer and she is willing to continue living with him, he must not leave her.
References for 1 Corinthians 7:12
And if a believing woman has a husband who is not a believer and he is willing to continue living with her, she must not leave him.
