1 Corinthians 7:1-5

Now concerning the things whereof ye wrote unto me: It is good for a man not to touch a woman.

Nevertheless, to avoid fornication, let every man have his own wife, and let every woman have her own husband.

Let the husband render unto the wife due benevolence: and likewise also the wife unto the husband.

The wife hath not power of her own body, but the husband: and likewise also the husband hath not power of his own body, but the wife.

Defraud ye not one the other, except it be with consent for a time, that ye may give yourselves to fasting and prayer; and come together again, that Satan tempt you not for your incontinency.
