As long as everyone involved is 100% honest, it can work very well. You are correct that your H doesn't have a females' body, so by finding a female partner that he is not threatened by would be your best choice. It can be done, but again I must stress that there can be no lies or deceptions...otherwise you are just cheating/sleeping around.
Poly also works for those whose primary partner is vanilla and you are looking for someone to explore your kink side. It doesn't mean you love your primary any less, you are just looking to add another piece that is not there.
I have found that I have grown closer to my spouse throughout these experiences. I have learned more about her in ways I could not bring out. However, by allowing her to explore certain desires with another partner, I have been able to modify how I treat her.
Our sessions are more passionate and her submission is deeper then it has ever been.
This does not work for everyone, but for those that it does...![]()
