1 Corinthians 7:2-4

2 But because of cases of sexual immorality, each man should have his own wife and each woman her own husband.
3 The husband should give to his wife her conjugal rights, and likewise the wife to her husband.
4 For 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.
