Swap wife, a helpless choice

I often see articles on the Internet that introduce the game of changing wives. At that time, I read it only exciting and never thought of taking part in it. In my opinion, my wife can only own it. How can other men touch it! Even if it’s exchange, it seems that I won’t lose. If someone else plays with my wife, I’ll also play with someone else’s wife. But I feel that even if I play with ten other people’s wives, as long as one person plays with my wife, I still feel that I can’t stand it.
