Tidalgender

Similar to the tides of an ocean, tidalgender is a gender that rises and falls in intensity every few hours, days, weeks, months, or even years. The lower levels of tidalgender are called low (gender) while the higher levels are called high (gender), so for example you could say you feel like you’re high stargender, or low demiboy, or even high genderflux and low genderfluid simultaneously.
