1 Corinthians 7:3, 5

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.

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.
