Cassgenderfae is a subset of cassgender where one feels that their gender is unimportant or where one is indifferent to the idea of gender, but knows that they don't have a male or masculine gender. Cassgenderfae is different from a lack of gender, as a cassgenderfae individual might have a gender but not feel that it's an important part of their identity. It can also be described as a combination of cassgender and genderfae.
The masculine counterpart is cassgenderfaun. A related term is cassflux, where the level of indifference fluctuates.
