1 Corinthians 7:1-9

1 Now concerning the things about which you wrote to me: it is good for a man not to touch a woman.  2 But, because of sexual immoralities, let each man have his own wife, and let each woman have her own husband.  3 Let the husband render to his wife the affection owed her, and likewise also the wife to her husband.  4 The wife doesn't have authority over her own body, but the husband. Likewise also the husband doesn't have authority over his own body, but the wife.  5 Don't deprive one another, unless it is by consent for a season, that you may give yourselves to fasting and prayer, and may be together again, that Satan doesn't tempt you because of your lack of self-control.

6 But this I say by way of concession, not of commandment.  7 Yet I wish that all men were like me. However each man has his own gift from God, one of this kind, and another of that kind.  8 But I say to the unmarried and to widows, it is good for them if they remain even as I am.  9 But if they don't have self-control, let them marry. For it's better to marry than to burn.
