Equibinary (equigender + binary): experiencing binary genders in equal amounts, in perfectly equal parts. They could be nongenders, eugenders, antigenders, etc.
Different from ambinary because equinary/equary quantifies binaries/arities as equal and it includes those who are exclusively abinary only, in the sense that they are equally distanced from both binary genders, they have equal binary nongenders/a-genders.
