domgender/plerugender- when one has multiple genders but a specific one is dominant above the rest

Domfluid/Plerufluid- When one is Dom/plerugender, but the dominant gender changes. So someone who is Domgender could feel that their dominant gender is female for a few months/for an X amount of time, but then their dominant gender changes to Agender for X amount of time.
