1 Corinthians 7:1-9

Now as to the matters of which you wrote: It is good (beneficial, advantageous) for a man not to touch a woman [outside marriage]. 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. The husband must fulfill his [marital] duty to his wife [with good will and kindness], and likewise the wife to her husband. 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. Do not deprive each other [of marital rights], except perhaps by mutual consent for a time, so that you may devote yourselves [unhindered] to prayer, but come together again so that Satan will not tempt you [to sin] because of your lack of self-control. But I am saying this as a concession, not as a command. I wish that all the people were as I am; but each person has his own gift from God, one of this kind and one of that. But I say to the unmarried and to the widows, [that as a practical matter] it is good if they remain [single and entirely devoted to the Lord] as I am. But if they do not have [sufficient] self-control, they should marry; for it is better to marry than to burn with passion.
