Not OP, obviously, but check out /r/polyamory for specific support and validation that it can and does happen regularly.

You say you talked to 'polygamous couples', by that, can I assume you mean families or some other word for more-than-two-people?

Did you talk to a wide variety of non-monogamous people, or was your focus mainly on the religious/pseudo-religious one-man-with-many-women compound sorts of relationships?
