Eugender: affirmative, operative, (ab)original, functional and valid genders, otherwise absolute genders accessible within your own culture and life experience (simultaneously or not). 

A counterpoint of ungender/antigender; when you have indeed that genderness, i.e. an euagender is verily agender. Eu- prefix comes from the Greek εὖ (eu, “well” or “true”). 

Some people can define a given eugender as another gender’s antigender for their own purposes. An euneutrois can be antigirl and antiagender. Useful for zerogender and cendgender people, as if antigender is antieugender Not be confused with gendergender, monogender or suptiligender.
