So a triad, where all three people have loving sex with the other two, but have no sex or romantic attachments outside the triad, would be poly but not open. So I disagree with M, who says above [not quoted] that poly is a subset of open.
Point taken. A poly-fi triad or quad would be non-monogamous, but closed. I meant to put poly-fi under the non-mono heading, not the open heading.
Love withers under constraint; its very essence is liberty. It is compatible neither with envy, jealousy or fear. It is there most pure, perfect and unlimited when its votaries live in confidence, equality and unreserve. -- Shelley
