My "perfect" poly is having a long-term committed romantic loving relationship with one or more people who can respect each other for who they are with no attempts to manipulate or change the others - I think that from a purely practical standpoint my limit is two (Based on current experiences). Living arrangements are negotiable as is whether the two of them have anything beyond a functioning friendship. If they choose to bring others into the relationship then that is totally cool by me too, and I don't mind what sex their partners are.
I don't know that I focus quite so much on "perfect", though - I think I have some needs which a relationship configuration needs to fill, and some wants over and above that. As long as the needs are met (and everyone else's who is involved) then I think I cam quite flexible.
I feel blessed to have a wonderful relationship like this for over a year and a half now. I have had others that have been learning opportunities and good in themselves but this one is by far the best.
Thanks for asking!
