Anyone give permission to their boyfriend/girlfriend to flirt with a stranger? - Monogomish?

So to start my partner and I are monogomish (emotionally committed, but have sex with other people together that we agree on). I get turned on sexually when I see my partner enjoying having sex with other people. I want to know if anyone has let their partner flirt with a stranger at a club/bar? And if so, how did it go?
