So you are committing adultery, and the virgin you abandoned, if she is married is also committing adultery, and the man who married the virgin you abandoned is committing adultery., so you have really left quite a trail behind you, so I understand why you are trying so hard to bring a different meaning into marriage.
So, I abandoned the virgin. (Well, she wasn't a virgin at the time I abandoned her, but I think you get that.) And in the eyes of God we were married, it would seem.
But wait. If I go back to my first sex partner, she had sex with, and abandoned, a virgin (i.e. me). So, weren't we married? So when I had sex with a virgin, I was already married, so I couldn't be married to Laura (the virgin) because I was already married to Jane. But wait. Jane wasn't a virgin when we had sex, so Jane and I couldn't be married, because she must have already been married.
Or is this one of those cases where we have some male/female asymmetry going on? Is it that the first time a male has sex with a female virgin, they are married? Oh, wait. What if a virgin man has sex with a virgin woman? Married. Clearly. Then he, no longer a virgin, has sex with another virgin woman. Now what? Who is married to whom?
As I said before, we're asking you to put a little thought into this. The Bible describes what the authors thought was an ideal way of living, and there's an awful lot to be said for mating for life, and not abandoning sex partners along the way. We may not all agree with the advice of the Bible, but it's consistent and not ridiculous. However, you've twisted that good advice on the best way to live into some sort of spellcasting magic that occurs when penises enter vaginas.
And even if the world reverts to the sort of ideal world that enforces God's law among men, it won't change the fact that people will still commit adultery, and virgins will still sell themselves as sex partners to married men. Maybe they will be stoned to death when they are caught, which ought to keep that sort of thing to a minimum, but it will still happen, just like it does in Iran, or Saudi Arabia, or ISIS-held lands where they do that sort of thing even today. So, beheadings and stonings don't really solve the problem. The Bible says that men and women should be married in order to have sex, but this magic part is your own invention.
