Eugender

Eugender (pronounced "ev-gender" or "ef-gender", from the Greek εὖ) is any absolute, affirmative gender, it is opposed to antigender. It is a positive and certain gender experience, where one is certain that they are a given gender. It is also useful for some individuals to define a given pair of genders as an eugender-antigender pair within their gender experience.

Generally the eu- prefix is not necessary, as any gender without the anti- prefix can be assumed to be a eugender (in the same way numbers usually do not have to be specified as being positive), but in can be helpful to specify in some situations. For example girl (or eugirl) would be the eugender of antigirl.
