Polyamory

I didn't come up with this term/thread, I actually copied it from the poly and kinky group in fetlife. You can find the discussion there but I'll tell you how the OP defined these terms:

Relationship Collage - with this one, you believe that your relationships should together meet your needs. That means, for example if you are not sexually satisfied in one relationship, you seek another to fulfill that specific need

Relationship Complete - with this one, you believe that your relationships should be complete and fulfill most (if not all) of your basic relationship needs on their own. That means for example, if you are not sexually satisfied in one relationship, you might consider terminating or de-esclating the relationship
