Overview
What fluidflux means.
Two things move. Which gender you are, and how much of it is there.
Genderfluid covers the first. Genderflux covers the second. Fluidflux is both dials at once — you move between genders, and the strength of whatever you land on rises and falls as well.
So it isn't just man on Tuesday, woman on Friday. It's man at half volume on Tuesday. Something with no name and barely any weight on Wednesday. Woman on Friday, loud enough that the wrong shirt is unbearable.
Plain about the word: fluidflux is small. It was put together in online microlabel spaces, and almost everything written about it is a one-line definition rather than anyone's actual life. The two halves — fluid, flux — are far better documented than the combination. Some people also think the word is unnecessary, and that saying "genderfluid and genderflux" does the same job. That argument is live and nobody has won it.
What follows is the mechanics, and how people who live with both dials tend to describe it. If only one dial moves for you, there is a better-fitting page and you should go and read that one instead.
Combination of genderfluid and genderflux—both the gender identity and its intensity change over time.

Origin
Where the word comes from
Fluidflux is a portmanteau/combination label built from genderfluid and genderflux, describing a gender that both moves between identities and varies in intensity as it does. Sources disagree on its coiner and date: some community wikis credit an August 2014 coining to Tumblr users genderabbit and trigenby, while others attribute it to Tumblr user Xeno-Aligned around 2019, and the LGBTQIA+ Wiki notes its own entry could not be independently verified.
Because of that inconsistency, this page treats fluidflux as a well-attested community label with a genuinely contested history rather than pinning it to one origin story.
Signs people describe
Common experiences
None of these is a test. Most people recognise a few and shrug at the rest.
You have two questions in the morning, not one.
What am I, and how much of it is there.
You say "a bit", "partly", "sort of" about your own gender, and you mean it literally rather than as hedging.
You dressed for who you were at eight and it was wrong by three.
A haircut that was right for a fortnight becomes a stranger's head, and you couldn't say which day it flipped.
You keep clothes you haven't touched in months and won't get rid of, because you know that person comes back.
Correcting someone's pronouns feels less like a fight and more like paperwork you'll have to redo.
There are days with nothing there at all, and you've wondered whether the nothing is the truth and the rest is a story you tell.
Forms are a lottery.
The honest answer on Tuesday is a lie today.
You read about being genderfluid, nodded along, then got stuck on the part where the gender always seems to arrive whole.
You keep a note, a tracker, a colour on a calendar — because the pattern is only visible across weeks and you got tired of arguing with yourself.
You've been told you're overthinking it by people who have never once had to think about it.
Day to day
What it looks like on a normal Tuesday
Wake up and check. Not a ceremony — more like glancing at the weather through a window. Two readings: which, and how much.
Say today it's a man, at about half. Enough that the shirt is right and the name people use for you is fine. Not enough to bother anyone about. Most days are like this. Most days nobody could tell.
You get dressed for half. By lunch it has dropped further, and your reflection in a shop window is nobody in particular. Neutral. Faintly irritating. Not worth a crisis.
Then something small lands wrong. Someone calls you "mate" and it's fine. Two hours later the same word from the same person makes you flinch, and you can't explain why the second time and not the first. The dial moved in between.
Evening, you change into whatever costs nothing. Maybe you note it down, because the pattern only makes sense across weeks and you've stopped trusting your memory of last Thursday.
Some days there's no reading at all. Nothing comes back. You get up, get things done, and feel slightly like a stranger renting your own life.

Straight answers
What people get wrong
Just make your mind up.
There's nothing to make up. Nothing is being decided — something is being reported. Asking you to settle is asking you to pick one week and lie about the other fifty-one.
If it changes, it isn't real.
Appetite changes. Energy changes. Nobody calls those fake. Gender sitting still in most people doesn't make movement a fault.
The empty days are the truth and the rest is performance.
Low is a setting on the same dial, not the bedrock under it. If nothing ever came back, you'd be agender. Things come back.
You must switch every day, or it doesn't count.
There is no required speed. Hours for some people, months for others. A whole season still, then three changes in a fortnight.
You can't medically transition — you'd regret it.
Plenty of people do transition. The usual approach is choosing for the whole range rather than the loudest day. Take it slowly because it's your body, not because someone else doubts you.
It's a microlabel, so someone invented it and it doesn't count.
Every word for gender was invented by somebody. The only question is whether it describes what happens to you. If it's more machinery than you need, "genderfluid" in public and the long version in private is a perfectly normal way to live.
Take care
On the hard days
The worst is the flat day. Nothing in the room, nothing to point at, and the whole thing feels like something you invented for attention. That feeling is not evidence. The dial is reading low. It isn't reading the truth.
Second worst: the day it arrives loud and you're already dressed, already out, already somewhere you can't do a thing about it for nine hours.
Then the admin. Being asked again. Explaining again. Watching someone's face do the small calculation of whether to bother.
And the grief nobody warns you about — that this doesn't resolve. There's no settled version of you waiting at the end of it. Some people find that unbearable for a while, then stop noticing.
Two things people say help. Keep something physical from each setting, so the low days have proof. And find one person who never asks which one you are today.
If the flat days have stopped ending, and it isn't only gender that's gone quiet — sleep, food, wanting anything at all — that's worth taking to someone, separately from any of this.
Pronouns
Pronouns
People using this word land all over the place. Some cycle pronouns with the change. Some keep one set permanently, precisely because everything else moves. Some list two or three and let people pick whichever.
A common arrangement: one public set that never changes, and a small circle who get told which day it is. That isn't a compromise you owe anyone an explanation for.
If you speak a language where verbs and adjectives carry gender, this was never a pronoun question. It's a whole-sentence question, and you're doing far more work than an English speaker with the same gender.
Consider another path
This might not be your word if…
- 1Only your presentation moves. Trousers some weeks, eyeliner others, and underneath it's the same gender all year. That's presentation, and it isn't flux.
- 2Your range never leaves one gender. Woman, then less of one, then nothing, then woman again. That's girlflux, and the word exists for a reason.
- 3The strength never changes. You switch, but every setting shows up at full volume. Genderfluid covers that cleanly and with far more company.
- 4It's always the same two genders, both fully there. Look at bigender first.
- 5Everything feels unstable because you started asking these questions six weeks ago. Early on, everything wobbles. That wobble usually settles into something with a simpler name. Give it time before you build machinery.
- 6What actually moves is your mood, and gender is what the mood grabs onto. Worth being honest about — if the low days come with everything else going flat too, the pattern may be about something other than gender, and no label will touch it.
- 7You like the word more than the description. That's allowed, but read the description again first. A word that fits badly costs you every single time you use it.
Close by
Related identities
Genderfluid
One dial: which gender. You move, but whatever you land on arrives whole. If the strength never varies, this is your word — and it's a much larger, far better documented community than this one.
ReadGenderflux
The other dial on its own. Intensity rises and falls, but it's the same gender underneath the whole time. Fluidflux adds movement between different genders.
ReadGirlflux / boyflux
Flux inside one binary gender. If your range runs woman, then less of one, then nothing, then back — and never crosses into anything else — that's girlflux. Same shape for boyflux.
Bigender
Two genders, often both present or alternating between two fixed points. Bigender describes how many. Fluidflux describes the movement and the volume.
ReadGenderfae / genderfaun
Fluid, but with part of the range fenced off — genderfae never fully male, genderfaun never fully female. That's a restriction on where the fluidity can go, not a second dial. Some people are both this and fluidflux.
Demifluid / demiflux
Something stays fixed while the rest moves or varies in strength. If there's a stable core underneath everything that shifts, start here.
Agender / neutrois
No gender, and it stays that way. Fluidflux can pass through nothing at all — it just doesn't stay there.
Abrosexual
Attraction that changes over time. A completely different axis: who you want, not what you are. Some people are both, and mix the two up at first.
Non-binary
The umbrella most fluidflux people sit under. Though someone whose range only ever covers man and woman may not use it for themselves, and that's consistent.
Questions people ask
Frequently asked questions
What's the difference between genderfluid and fluidflux?+
Genderfluid is one dial: which gender. Fluidflux is two: which gender, and how much of it. Man on Monday, woman on Friday, both arriving whole — that's genderfluid. A faint half-man on Monday and a deafening Friday — that's the second dial. Most fluidflux people still say "genderfluid" in public, because it's shorter and people already know it.
Can I take hormones or have surgery if my gender keeps changing?+
Yes, people do. The usual approach is choosing for the whole range rather than the loudest day — the body that hurts least across every setting. Expect gatekeeping: some clinicians want a straight-line story, and "it changes" is not the story they were trained on. Many people simplify what they say in that room. That's a survival decision, not a lie about yourself.
Is fluidflux a real identity or just a made-up internet microlabel?+
Both are true and neither settles it. The word came out of online microlabel spaces and there's very little written about actually living as it — mostly one-line definitions copied between wikis. The experience it points at, fluid plus flux, is described by plenty of people under two older words. If it lets you say a true thing quickly, it's doing its job. If it's more parts than you need, drop it.
How do I know this isn't just mood swings?+
Ask what's moving. In a mood swing, how you feel about your gender shifts — the same gender feels better or worse. Here, the gender itself moves, and it can move while your mood sits completely flat. If you're unsure, track it: two lines a day, which and how much. What's invisible over a week is obvious over eight.
