I am sorry it came off that way. I was afraid it might. I obviously don't know how to explain it very well. You are correct, of course extroverts feelings are as deep and as real as an introverts. It is just that when introverts interact with other people they tend to focus on a few things and want to know details and as much as possible and those interactions consume their energy. When extroverts interact they tend to go for breath and they are energized by their interactions. Of course neither is completely true to the exclusion of the other. But it is why extroverts enjoy parties and introverts are wall flowers. We just see and interact with people differently. I thought that perhaps that would give extroverts the advantage in a poly relationship as they can field and interact with more people at once.
I just reread my original post. I think the difference I see is between what deuseri had with a couple and poly households that are more like communal living. I would think that the love between a sub and married Doms would be like the love a child has for their parents. Again I don't mean to offend by saying your love was a childish love. I am just trying to put it into relationship terms I can understand.
