Today with many committed couples not seeking formal marriage, the term
is frequently generalized to open relationship. The concept of being
sexually open versus closed is also sometimes applied to triads or
other groups larger than two.
Open relationships are sometimes considered a (very common) form of
polyamory (involvement in loving relationships, of a sexual kind, with
more than one person), and sometimes considered to be broader than
polyamory by including sexual play outside the context of loving
relationships. Certainly there is at least much potential overlap.
