I think sharing partners, for some of us, is the ultimate level of trust and honesty. Some people get married and never desire the company of any one other than there spouse, and that’s great, but a lot of men and women love there spouse, but let’s be honest, a little change in the menu is nice. Having a partner that both shares that opinion, and is honest enough to say “ Hey, I love you, I love our family, and this life we’ve created for ourselves! However, momma wouldn’t mind some strange dick(s), and I know daddy wouldn’t mind a little piece! Let’s get it together !” Many men stray outside there marriage and go behind there wives backs seeking that exact thing! I think I’m lucky enough to have a partner that has the same POV as I do about sex! Also my wife likes woman, this has been fruitful to me and my penis, if she wants a little side dick she’s earned it!
