Triasexual

Triasexual (shortened to Tria) is an orientation for anyone of any gender who is exclusively attracted to any non-binary people and/or identities. A triasexual person does not have to be attracted to all types of non-binary people, they might only be attracted to certain types of non-binary people. Anyone can identify as triasexual as long as they aren't attracted to binary people.

Triasexual was created as an alternative for ceterosexual, to avoid the debate surrounding who can and cannot identify as ceterosexual.

Flag
The term and flag were collectively coined on the LGBTA Wikia Discord server on July 27, 2020. The flag's meanings are as follows:

The purple represents non-binary identities that are connected to and/or are a mix of femininity and masculinity, because pink and blue mixed together make purple (pink and blue commonly represent femininity and masculinity). The yellow represents abinary people and identities. The green represents atrinary identities, including xenogender people, as well as representing neutrois and agender people. The white represents love and/or attraction.

Etymology
The word tria- means "third" in Esperanto, referencing how non-binary identities are commonly referred to as a third gender.
