1 Corinthians 7:1-6

Now I will discuss the things you wrote me about. It is good for a man not to have sexual relations with a woman. But because sexual sin is a danger, each man should have his own wife, and each woman should have her own husband. The husband should give his wife all that he owes her as his wife. And the wife should give her husband all that she owes him as her husband. The wife does not have full rights over her own body; her husband shares them. And the husband does not have full rights over his own body; his wife shares them. Do not refuse to give your bodies to each other, unless you both agree to stay away from sexual relations for a time so you can give your time to prayer. Then come together again so Satan cannot tempt you because of a lack of self-control. I say this to give you permission to stay away from sexual relations for a time. It is not a command to do so.
