A polycule is a group of people who are romantically involved with each other. This could involve several people, such as a triad of three individuals or more complex arrangements such as a quad, a V-shape or a network of even more people.

This type of non-monogamous involves more than two individuals who engage in simultaneous, multiple and consenting romantic relationships.

Although there are various configurations, polycules all require a lot of communication, honesty and trust to function. If those involved are honest with their needs, wants, and expectations, a polycule can thrive.
