I wouldn't be in one personally, but I couldn't care less if other consenting adults do. If three or more consenting, competent adults choose to enter a polyamorous relationship, who am I to stop them?
I would. I been strongly attracted to two people at the same time. Of course the favor should be returned among each other, and for that reason I doubt it would succeed for me.
Tbh, I have a friend who does poly stuff. It honestly just sounds like a rather selfish and greedy thing to me on it's own, but if you have others willing to do it with you than why not? The basic premise of what she told me is that she just "isn't satisfied" with one person, which is fine, I just don't see the world in that way.
