Genderfluid Pride Flag
Someone who is genderfluid is a person whose gender identity (the gender they identify with most) is not fixed. It can change over time or from day-to-day. Fluid is a form of gender identity or gender expression, rather than a sexual orientation.
Pink and blue represent femininity and masculinity, while purple is inclusive of both masculinity and femininity. Meanwhile, the black stripe stands for those who do not associate with any gender, while the white stripe includes all genders.
