Actually Paul does say something pretty close to have all the sex you want. He goes on to say that the man’s body does not belong to him but to his wife and vice-versa. He also says to not deny yourself from each other so you will not burn with desire. It sounds like Paul understands sex very well and approves of it.
Of course he is speaking of married people.
Also, Matthew 19:10 His disciples say unto him: If the case of a man with his wife be so, it is not expedient to marry. Who said to them: All men take not this word, but they to whom it is given. For there are eunuchs, who were born so from their mothers womb: and there are eunuchs, who were made so by men: and there are eunuchs, who have made themselves eunuchs for the kingdom of heaven. He that can take, let him take it.
Now to the unmarried and the widows I say: It is good for them to stay unmarried, as I am. But if they cannot control themselves, they should marry, for it is better to marry than to burn with passion.And again, he reiterates:
Brothers, each man, as responsible to God, should remain in the situation God called him to.
Now about virgins: I have no command from the Lord, but I give a judgment as one who by the Lord's mercy is trustworthy. Because of the present crisis, I think that it is good for you to remain as you are. Are you married? Do not seek a divorce. Are you unmarried? Do not look for a wife. But if you do marry, you have not sinned; and if a virgin marries, she has not sinned. But those who marry will face many troubles in this life, and I want to spare you this.
What I mean, brothers, is that the time is short. From now on those who have wives should live as if they had none; those who mourn, as if they did not; those who are happy, as if they were not; those who buy something, as if it were not theirs to keep; those who use the things of the world, as if not engrossed in them. For this world in its present form is passing away.
I would like you to be free from concern. An unmarried man is concerned about the Lord's affairs—how he can please the Lord. But a married man is concerned about the affairs of this world—how he can please his wife— and his interests are divided. An unmarried woman or virgin is concerned about the Lord's affairs: Her aim is to be devoted to the Lord in both body and spirit. But a married woman is concerned about the affairs of this world—how she can please her husband. I am saying this for your own good, not to restrict you, but that you may live in a right way in undivided devotion to the Lord.
If anyone thinks he is acting improperly toward the virgin he is engaged to, and if she is getting along in years and he feels he ought to marry, he should do as he wants. He is not sinning. They should get married. But the man who has settled the matter in his own mind, who is under no compulsion but has control over his own will, and who has made up his mind not to marry the virgin—this man also does the right thing. So then, he who marries the virgin does right, but he who does not marry her does even better.
A woman is bound to her husband as long as he lives. But if her husband dies, she is free to marry anyone she wishes, but he must belong to the Lord. In my judgment, she is happier if she stays as she is—and I think that I too have the Spirit of God.
Smart man. If I may be so bold, do you have a wife and use this as a reason if she isn’t in the mood?
