what you tell is just not right in this one. it can be done and works. I don't try to manage the woman, it doesn't work and is abusive if applying enough force to get the job done. just sanitize the environment. a foursome in front of me would never happen, but I get what your telling, and its completely wrong.You can't manage your environment Holmes. Any boundaries you set in your marriage, including no cheating, is coercive control and abuse.
Your wife can have a foursome in front of you, and there's absolutely nothing you can do about it. Cope with it.
I can and do. anyway, nice chatting w/ you.
