As soon as you disassociate sex from gender all hell breaks loose.

Anyway, Androgyneflux seems to include Agender-inity in its description (see here). So I guess yes. Coming from a non-helpful non-expert btw so take it with a grain of salt.

am I able to be both agender and androgyneflux?

Yep!

(Why I wrote this: To explain how "androgyneflux agender" isn't an oxymoron.)

<im:mgm> The state of being agender is the lack of gender, but not of gender quality.

This means you can identify as masc, fem, and neutral, while still lacking gender. Women aren't always fem, men aren't always masc, and enben aren't always neutral.

Even if you have a gender, you don't need to have a gender quality. Agenrine women, men, and enben are totally valid.

I made two other posts explaining why gender quality is a seperate part of your gender identity. It's like like the split attraction model, but for gender. (Link 1, Link 2)
