Genderbalanced
Genderbalanced is a multigender identity in which one has multiple genders and feels that they are perfectly balanced. This doesn't necessarily mean that their genders are all equal in size/prominence, just that their gender is perfectly balanced for them.
A form of genderbalanced specific to bigender individuals whose genders are male and female is omegagender.
