Contraic

Contraic is "opposite" gender attraction for non-binary individuals. For example, a demiboy attracted to demigirls may consider themselves to be contraic. They may also be attracted to similar genders such as librafeminine or paragirl, depending on what a contraic person considers to be the "opposite" gender. Not all non-binary genders have obvious opposites, and therefore, what "opposite" means can be defined by the user.

The opposite of contraic is symmaic.
