1 Corinthians 7:2-4

2 But because of sexual immoralities, each man is to have his own wife, and each woman is to have her own husband.

3 The husband must fulfill his duty to his wife, and likewise the wife also to her husband.

4 The wife does not have authority over her own body, but the husband does; and likewise the husband also does not have authority over his own body, but the wife does.
