That was true for us. I had assumed when we first began down this path she could quit if it wasn't the way I imagined and wished her to stop. I don't want her to quit dating other men, but she has often reminded me was my idea and that she can't go back to the way it was. She says if I asked her now to try going back, she is sure she would just keep fucking guys and stop telling me about it.
This is a "Be careful what you ask for" life. Your lives are most likely change forever. It's true that some can back out but if the wife's mind-blowing reaction to that first time is like mine, it can't be undone. That freedom is addictive and there's no pill to help her return to monogamy. I love her eagerness for other dicks and quickly got over that initial jealousy during her first few fuckings that almost always comes about. Some men think they won't be jealous when they see their wives fucking or when she goes out on a date without them are in for a surprise.
