Welcome to the forum.
My only advice at this stage, other than the learning that you are trying to do, is not to let this go too far in your mind before you talk to your wife. If your wife says that this is a "no way!" then you can stop spending the time doing the research. Also, the more your wife perceives you have gone down this road, the more threatened she will feel.
But you don't have to bring it up directly about you - I have posted before about some celebrities that are poly - maybe talk with her about them in some natural way and see what sort of reaction you get.
