Enbian

Enbian Pride

Enbian, also known as Non-Binary Loving Non-Binary (NBLNB) is a diamoric orientation that refers to non-binary people attracted to non-binary people. One may or may not be attracted to other genders as well. This attraction does not need to be exclusive, as the label is used in a way to unify all non-binary people who love other non-binary people.
