1 Corinthians 7:3-5

3 Let the husband render to the wife due affection, and likewise the wife to the husband.

4 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.

5 Do not deprive one another except with consent for a time, that you may give yourselves to fasting and prayer. Then come together again, so that Satan does not tempt you for lack of self-control.
