Proud Cubes Series - 1st Edition - Polyamory Signature Proud Cube Polyamory is a form of consensual non-monogamy. Consensual non-monogamy involves relationships consisting of more than 2 people, with the approval of everyone in the relationship. It is a common misconception that polyamory people are cheating in their relationships. It isn't considered cheating because cheating involves deception and betrayal, whereas in a polyamory relationship everything should be communicated openly. Meaning of the colors in the Polyamory Flag: Blue stands for openness and honesty amongst all partners. Red stands for love and passio. Back represents solidarity with those who must hide their polyamorous relationships from the world.
