It is known to us, males, how we like to show off our sexy wife to others. It's not always swinging we seek. Swinging is about changing the boring partner or the unattractive partner and getting the taste of a new one. A real confident fantasy is when couples like to show off their activities to single males and enjoy the exhibition. Exhibition to the world and and exposing your wife's flesh to everyone lowers one's self respect. But letting one single guy watch you two make love in your erotic way, enjoying how he desires your other half and not being able to do her is a real man's Fantasy. This is confidence. And I am not making it up I faced it and so did the researchers. If any desi couple interested to try, I'll be available for tips. Thank you, hope this helps.
