King James Bible
1Now concerning the things whereof ye wrote unto me: It is good for a man not to touch a woman.
2Nevertheless, to avoid fornication, let every man have his own wife, and let every woman have her own husband.
3Let the husband render unto the wife due benevolence: and likewise also the wife unto the husband.
4The 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.
5Defraud 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.
6But I speak this by permission, and not of commandment.
7For I would that all men were even as I myself. But every man hath his proper gift of God, one after this manner, and another after that.
8I say therefore to the unmarried and widows, it is good for them if they abide even as I. 9But if they cannot contain, let them marry: for it is better to marry than to burn.
The Amplified Bible
1NOW AS to the matters of which you wrote me. It is well [and by that I mean advantageous, expedient, profitable, and wholesome] for a man not to touch a woman [to cohabit with her] but to remain unmarried.
2But because of the temptation to impurity and to avoid immorality, let each [man] have his own wife and let each [woman] have her own husband.
3The husband should give to his wife her conjugal rights (goodwill, kindness, and what is due her as his wife), and likewise the wife to her husband.
4For the wife does not have [exclusive] authority and control over her own body, but the husband [has his rights]; likewise also the husband does not have [exclusive] authority and control over his body, but the wife [has her rights].
5Do not refuse and deprive and defraud each other [of your due marital rights], except perhaps by mutual consent for a time, so that you may devote yourselves unhindered to prayer. But afterwards resume marital relations, lest Satan tempt you [to sin] through your lack of restraint of sexual desire.
6But I am saying this more as a matter of permission and concession, not as a command or regulation.
7I wish that all men were like I myself am [in this matter of self-control]. But each has his own special gift from God, one of this kind and one of another.
8But to the unmarried people and to the widows, I declare that it is well (good, advantageous, expedient, and wholesome) for them to remain [single] even as I do. 9But if they have not self-control (restraint of their passions), they should marry. For it is better to marry than to be aflame [with passion and tortured continually with ungratified desire].
The Message Bible
1 Now, getting down to the questions you asked in your letter to me. First, Is it a good thing to have sexual relations? 2-6Certainly—but only within a certain context. It's good for a man to have a wife, and for a woman to have a husband. Sexual drives are strong, but marriage is strong enough to contain them and provide for a balanced and fulfilling sexual life in a world of sexual disorder. The marriage bed must be a place of mutuality—the husband seeking to satisfy his wife, the wife seeking to satisfy her husband. Marriage is not a place to "stand up for your rights." Marriage is a decision to serve the other, whether in bed or out. Abstaining from sex is permissible for a period of time if you both agree to it, and if it's for the purposes of prayer and fasting—but only for such times. Then come back together again. Satan has an ingenious way of tempting us when we least expect it. I'm not, understand, commanding these periods of abstinence—only providing my best counsel if you should choose them. 7Sometimes I wish everyone were single like me—a simpler life in many ways! But celibacy is not for everyone any more than marriage is. God gives the gift of the single life to some, the gift of the married life to others.
8-9I do, though, tell the unmarried and widows that singleness might well be the best thing for them, as it has been for me. But if they can't manage their desires and emotions, they should by all means go ahead and get married. The difficulties of marriage are preferable by far to a sexually tortured life as a single.
