I think the translation is causing problems. Here are a few others.
[7:1] Now concerning the matters about which you wrote: “It is good for a man not to have sexual relations with a woman.”  But because of the temptation to sexual immorality, each man should have his own wife and each woman her own husband.  The husband should give to his wife her conjugal rights, and likewise the wife to her husband.  For the wife does not have authority over her own body, but the husband does. Likewise the husband does not have authority over his own body, but the wife does.  Do not deprive one another, except perhaps by agreement for a limited time, that you may devote yourselves to prayer; but then come together again, so that Satan may not tempt you because of your lack of self-control.
 Now as a concession, not a command, I say this.  I wish that all were as I myself am. But each has his own gift from God, one of one kind and one of another.
 To the unmarried and the widows I say that it is good for them to remain single as I am.  But if they cannot exercise self-control, they should marry. For it is better to marry than to burn with passion.
 To the married I give this charge (not I, but the Lord): the wife should not separate from her husband  (but if she does, she should remain unmarried or else be reconciled to her husband), and the husband should not divorce his wife.
 To the rest I say (I, not the Lord) that if any brother has a wife who is an unbeliever, and she consents to live with him, he should not divorce her.  If any woman has a husband who is an unbeliever, and he consents to live with her, she should not divorce him.  For the unbelieving husband is made holy because of his wife, and the unbelieving wife is made holy because of her husband. Otherwise your children would be unclean, but as it is, they are holy.  But if the unbelieving partner separates, let it be so. In such cases the brother or sister is not enslaved. God has called you to peace.  For how do you know, wife, whether you will save your husband? Or how do you know, husband, whether you will save your wife?
(1 Corinthians 7:1-16 ESV)
 Now concerning the thing whereof you wrote to me: It is good for a man not to touch a woman.  But for fear of fornication, let every man have his own wife, and let every woman have her own husband.  Let the husband render the debt to his wife, and the wife also in like manner to the husband.  The wife hath not power of her own body, but the husband. And in like manner the husband also hath not power of his own body, but the wife.  Defraud not one another, except, perhaps, by consent, for a time, that you may give yourselves to prayer; and return together again, lest Satan tempt you for your incontinency.
 But I speak this by indulgence, not by commandment.  For I would that all men were even as myself: but every one hath his proper gift from God; one after this manner, and another after that.  But I say to the unmarried, and to the widows: It is good for them if they so continue, even as I.  But if they do not contain themselves, let them marry. For it is better to marry than to be burnt.  But to them that are married, not I but the Lord commandeth, that the wife depart not from her husband.
 And if she depart, that she remain unmarried, or be reconciled to her husband. And let not the husband put away his wife.  For to the rest I speak, not the Lord. If any brother hath a wife that believeth not, and she consent to dwell with him, let him not put her away.  And if any woman hath a husband that believeth not, and he consent to dwell with her, let her not put away her husband.  For the unbelieving husband is sanctified by the believing wife; and the unbelieving wife is sanctified by the believing husband: otherwise your children should be unclean; but now they are holy.  But if the unbeliever depart, let him depart. For a brother or sister is not under servitude in such cases. But God hath called us in peace.
Does this help any?
