1 Corinthians 7:3-5

3A husband should fulfill his marital duty to his wife, and likewise a wife to her husband.

4A wife does not have the right over her own body, but her husband does. In the same way, a husband does not have the right over his own body, but his wife does.

5Do not deprive one another — except when you agree for a time, to devote yourselves to prayer. Then come together again; otherwise, Satan may tempt you because of your lack of self-control.
