6 But I say this as a concession, not as a commandment. 7 For I wish that all men were even as I myself. But each one has his own gift from God, one in this manner and another in that.
Sex is a mutual gift from God... and as noted... when difficulties arise, sex is about concessions... not commandments. There is no leader and follower in this realm.
I know this is an old thread, but for anyone who might be reading it...
The marrying / taking a sexual partner is the optional part. Paul is telling the Corinthians that he wishes they were like him (unmarried), because unmarried people can devote themselves to the things of God whereas married people have to devote themselves to the things of the world.
What you are suggesting is a contradiction. You can't have "do not deprive" (wich has a connotation of withholding from someone that which he or she is due) followed by "it's a suggestion" (so go ahead and deprive if you feel like it).
IMO, the clear meaning of the whole passage is that all (men and women alike) owe sex to their spouses. And that sex needs to be of a sufficient quality and quantity that our spouses are satisfied (so you are not tempted to sin).
If you don't have sexual cravings, stay single and serve God. If the lack of sexual craving is not your "gift" (meaning, such a lack is not the norm) go ahead and marry to avoid sin. But know that since condoned sex is a primary reason to marry, you marry with the understanding that you are making a commitment to your spouse to fulfill that need.
