2But because sexual immorality is so common, each man should have sexual relations with his own wife, and each woman should have sexual relations with her own husband.
4A wife does not have the right over her own body, but her husband does. In the same way, a husband does not have the right over his own body, but his wife does.
5Do not deprive one another--except when you agree for a time, to devote yourselves to prayer. Then come together again; otherwise, Satan may tempt you because of your lack of self-control.
14For the unbelieving husband is made holy by the wife, and the unbelieving wife is made holy by the husband. Otherwise your children would be unclean, but as it is they are holy.
18Was anyone already circumcised when he was called? He should not undo his circumcision. Was anyone called while uncircumcised? He should not get circumcised.
28However, if you do get married, you have not sinned, and if a virgin marries, she has not sinned. But such people will have trouble in this life, and I am trying to spare you.
34and his interests are divided. The unmarried woman or virgin is concerned about the things of the Lord, so that she may be holy both in body and in spirit. But the married woman is concerned about the things of the world--how she may please her husband.
35I am saying this for your own benefit, not to put a restraint on you, but to promote what is proper and so that you may be devoted to the Lord without distraction.
36If any man thinks he is acting improperly toward the virgin he is engaged to, if she is getting beyond the usual age for marriage, and he feels he should marry--he can do what he wants. He is not sinning; they can get married.
37But he who stands firm in his heart (who is under no compulsion, but has control over his own will) and has decided in his heart to keep her as his fianc, will do well.
