this sets up the incentives very nicely, i enjoy wingmanning for my partners. dont wanna be there, dont want a threesome, just wanna hear about it afterwards.
I guess because it is like you are stealing it from her and that she is approving him as a sex deserving man. If more women approve him then you like him more.
I've never done any wingmanning for my partners, but there's something that's uniquely bonding when both of us come home and tell each other about the night we spent with someone else. It's just a level of intimacy I never felt in monogamy
