Much as marriage is now a contract between two people in a ritual performed by people and has also left it's meaning as a commitment to God. The term also referred to a vaulted cellar or similar place where prostitutes plied their trade. Excerpted from The American Heritage Dictionary of the English Language. Ive never personally met such a man that seemed free. He's true to the methods of control, and who he needs to portray to gain it.
Marriage is about loss of control.
Then one becomes the lie. The lesson seems obvious. But hey, maybe it's complicated. Sex outside the bond of marriage is not permitted at any time according to the Bible. It is a general term that refers to sexual immorality and does include sex outside of marriage but, as you rightly point out, can include hiring prostitutes and other sexual sins.
