What is Bigender?

Bigender is where a certain individual has two genders, for example male and female. It can also be used for people who identify with two genders at once.


How is it different from gender fluid?

A Genderfluid individual moves between two or more genders fluidly while a Bigender person stays with two genders and moves between those.  


How do i use correct pronouns?

Well, since they are moving between two genders normally they will have two different pronouns at different times, so just ask what their current pronouns are.
