Even if you have been having sex for years with many people, you can still become a "secondary virgin." That occurs when you repent of previous sexual sins and then determine not to be intimate with anyone until you are married. It will require discipline to stay in the hallway of doors, but it still bring the sweet benefits of healthiness, greater self-respect, and above all, harmony with the King. He will honor you for doing what is right.
It is far kinder and smarter to show someone a better path in life than to darkly follow down their's with the self-righteous belief that you do so with the purer intentions of justly punishing them for their previous actions, making you hypocritically the same and thus influencing further negative repercussions.
