1 Corinthians 7:2-4

Amplified Bible

² But because of [the temptation to participate in] sexual immorality, let each man have his own wife, and let each woman have her own husband. ³ The husband must fulfill his [marital] duty to his wife [with good will and kindness], and likewise the wife to her husband. ⁴ The wife does not have [exclusive] authority over her own body, but the husband shares with her; and likewise the husband does not have [exclusive] authority over his body, but the wife shares with him.
