Funnily enough, people who actually engage in wifesharing are usually a hell of a lot more confident than the people who need games that feature only one guy and a lot of girls in order to succeed
This inane comment reminds me of an ancient joke from the 90s:
A couple go to a 3 day holiday over by the sea. Once there, they agree to cheat on each-other two times. After both sides agreed - each side went their own way.
After the 3 days were up, they meet up before departure. The girl asks the guy, whether he cheated on her. He goes:
-"Yes. With a blonde and a brunette."
Then the guy asks her whether she cheated on him, and she goes:
-"Yes. With a military unit and a ships crew."
