1 Corinthians 7:3-5

3 The husband should fulfill his duty toward his wife, and likewise the wife toward her husband.

4 A wife does not have authority over her own body, but rather her husband, and similarly a husband does not have authority over his own body, but rather his wife.

5 Do not deprive each other, except perhaps by mutual consent for a time, to be free for prayer, but then return to one another, so that Satan may not tempt you through your lack of self-control.
