The Asexual Spectrum: Labels Grouped by What They Describe
Asexual spectrum labels grouped by what they describe: gray ace, demisexual, reciprosexual, akiosexual, aegosexual and aceflux, with survey data on each.

Table of Contents
The asexual spectrum is a set of words for people who feel little, rare, conditional or shifting sexual attraction. Gray-asexual, demisexual, reciprosexual, aegosexual and aceflux all sit under it, and each one answers a different question about attraction. Some describe how much of it a person feels. Others describe when it shows up, whether the person wants to act on it, or how it moves over time.
This guide sorts the labels by those questions instead of by the alphabet, because that is how people tell them apart in practice. Each entry gives a plain definition, the label it gets confused with, and survey numbers where any exist. It also looks at where these words come from and how much weight they can carry, which most glossaries skip.
Why ace is described as a spectrum and an umbrella
The umbrella: who the ace community includes
The Asexual Visibility and Education Network (AVEN) defines an asexual person as someone who does not feel sexual attraction. Such a person is not drawn to others sexually and does not want to act on attraction that way. Its FAQ then widens the circle. The “asexual umbrella” covers asexuality plus nearby identities, such as demisexuality and graysexuality, whose members share a broader community. “Ace” is the casual word for anyone under that umbrella.
So “ace” can mean two things. Sometimes it is short for asexual. More often it is shorthand for the whole group, which is why a gray-asexual person may say “I’m ace” without claiming to feel no attraction at all.
Why a spectrum instead of a yes-or-no
AVEN describes a broad range between “asexual” and “very sexual” rather than two boxes. Many people land in the space between, closer to the asexual end than most people are. AVEN notes that plenty of them still call themselves plain asexual, because it is easier to explain, especially when their rare attraction was brief.
That detail matters for how you read the rest of this page. Spectrum labels are optional extra precision. Nobody has to use one, and someone using “asexual” may have the same experience as someone else using “gray-ace.”
Sexual and romantic labels are separate
Most people on the ace umbrella use what AVEN calls the split attraction model: one label for sexual attraction and another for romantic attraction. A person can be asexual and heteroromantic, or graysexual and biromantic. Many asexual people also feel romantic, aesthetic or sensual pulls toward others, and those can point at a particular gender. Every label below describes sexual attraction only. Most have a romantic twin, such as demiromantic or aroflux. This page sticks to what each label means. Pride flags, including the gray-asexual and ace flags, are a matter of community symbolism rather than definition, so they are left out here.
The labels at a glance, grouped by what they describe
Each label on the ace spectrum answers one of four questions: how much attraction, under what conditions, whether the person wants to take part, and whether it changes. The table puts each label next to the one it is most often confused with.
| Label | What it describes | Closest neighbour | The one difference |
|---|---|---|---|
| Gray-asexual (grey ace) | Attraction that is rare, faint or tied to narrow circumstances | Asexual | Some attraction exists, even if seldom |
| Demisexual | Attraction only after an emotional bond forms | Gray-asexual | The trigger is a bond, not chance or low intensity |
| Reciprosexual | Attraction only after learning the other person is attracted first | Demisexual | The trigger is their interest, not closeness |
| Akiosexual / lithosexual | Attraction that is not wanted back and may fade if it is returned | Reciprosexual | Being wanted switches attraction off instead of on |
| Aegosexual | Arousal or fantasy with a gap between the self and the subject | Asexual | Sexual content can appeal while taking part does not |
| Aceflux | Attraction that moves between asexual, gray and allosexual levels | Gray-asexual | The level changes over time instead of staying low |
Two cautions apply to the whole table. The definitions come from community sources, mostly AVEN and a volunteer-edited wiki. And people often hold more than one of these labels at once, so the rows are not mutually exclusive.
Labels about how much attraction: gray-asexuality
Gray-asexual (grey ace)
Gray-asexual means feeling sexual attraction rarely, only in specific circumstances, or so faintly that it does not matter much in relationships. Spellings vary: graysexual, greysexual, gray-A, grey ace and “grace” all point to the same idea. The community wiki notes that some gray people feel attraction only once or twice in their lives.
The word also has a looser use. Some people treat it as a catch-all for any ace-spectrum identity that is not purely asexual, demisexual included. So when someone says “gray,” ask whether they mean the specific label or the whole middle ground.
The word is older than most spectrum terms. It grew out of AVEN forum talk in the 2000s, with “semisexuality” floated in 2003 and “gray-a” proposed in 2006.
How gray-ace differs from asexual and from low libido
The line with asexual is simple on paper: asexual means no sexual attraction, and gray means some, though not much. In practice the line is soft, as AVEN’s point about gray people who still say “asexual” shows.
The line with low libido runs on a different axis. Attraction is feeling drawn to a specific person. Libido, or sex drive, is a general bodily interest in sex. Medical News Today stresses that greysexuality is not the same thing as a low sex drive. Low desire can have a medical cause, and the same article treats it as a problem when it causes stress. A drop in interest that is new for you, or that bothers you, is worth raising with a doctor before reaching for a label.
Research backs the idea that gray is its own middle ground. In a peer-reviewed analysis of Ace Community Survey data, Copulsky and Hammack found asexual respondents scored lowest on sex drive and on willingness to have sex. Graysexual respondents scored lower than demisexual respondents on both measures.
How many people in the ace community use it
In the 2022 Ace Community Survey, 10.5% of ace respondents picked graysexual as their closest label. When allowed to tick every label that fit, 19.0% included it. The 2024 survey put the figure at 17.0%. These numbers describe people active in online ace spaces, not the general population, a limit covered further down.
Labels about when attraction can happen

Demisexual: attraction after a bond
Demisexual people feel sexual attraction only after an emotional bond has formed. AVEN separates this from simply choosing to wait: the attraction itself is absent until the bond exists. It is the best-known conditional label, used by 18.9% of ace respondents in the 2022 survey. Our full guide to demisexuality covers it in depth, so this entry stays short and serves as the reference point for the two labels below.
Reciprosexual: attraction after being wanted
A reciprosexual person does not feel sexual attraction unless they know the other person is attracted to them first. The word comes from “reciprocal,” and its romantic version is reciproromantic.
The nearest neighbour is demisexual, and the difference lies in what flips the switch. For a demisexual person, it is closeness built over time. For a reciprosexual person, it is learning that someone else is interested. That can happen with a near-stranger.
Picture a hypothetical case. Sam feels nothing toward a coworker for months. Then a friend mentions that the coworker has a crush on Sam, and attraction appears within days. Nothing about their bond changed. Only the knowledge did, which points toward reciprosexual rather than demisexual.
Akiosexual or lithosexual: attraction that fades when returned
This label is the mirror image of reciprosexual. The person may feel attraction but does not want it returned. Some feel uneasy at the thought of being desired, and the attraction can fade once they learn it is mutual. One glossary sums it up as wanting neither the attraction returned nor anyone being attracted to them.
The spelling is a mess, and the reason is a naming dispute. “Lithosexual” has been in use since at least April 2014. Some people argued that the prefix lith- borrowed from stone lesbian culture, so a Tumblr user proposed akoi- instead, giving “akoisexual”. Many stone lesbians pushed back on that claim, and both forms survive. Some glossaries spell it “akiosexual”, which is most likely a variant of akoisexual rather than a separate term.
Neither reciprosexual nor lithosexual had its own tick box in the 2022 Ace Community Survey. Both showed up only as write-in answers, alongside other rare terms such as fraysexual and acespike. So no reliable count exists for either.
Attraction without wanting to take part: aegosexual
Aegosexual: arousal with the self left out
Aegosexual describes a gap between a person and the subject of their arousal. Someone aegosexual may enjoy fantasies, erotic stories or other sexual content, yet feel little or no attraction to real people and no wish to be part of the act. Fantasies may leave the person out or be idealized. Adding realistic detail can make the scene less appealing.
The closest neighbour is plain asexual. Both groups may feel no pull toward actual partners. The difference is that sexual material can still land for an aegosexual person, as long as it stays at a distance. AVEN makes the related point that many asexual people experience some arousal, fantasy or masturbation, and that this does not cancel the label.
It is also more common than its obscurity suggests. In the 2022 Ace Community Survey, 13.1% of ace respondents ticked aegosexual or its older name, autochorissexual. Another 151 people wrote it in by hand when asked for their single closest label.
From a clinical paraphilia to a community label
This is one of the few spectrum labels that started in a journal. In 2012, psychologist Anthony Bogaert named “autochorissexualism,” meaning “identity-less” sexuality. He described it as a target-oriented paraphilia, a disconnect between a person’s identity and the target of arousal.
Ace communities took the idea but not the framing. “Aegosexual” was coined on Tumblr in November 2014. The aim was a word that was easier to say and dropped the paraphilia classification. One glossary puts it plainly: the community felt the original term pathologized the identity. The episode shows a pattern that runs through this whole topic. Researchers can name an experience, but people living it decide which name sticks.
Orchidsexual: a close cousin, not always a synonym
You will sometimes see orchidsexual given as another name for aegosexual. The community wiki keeps them apart. An orchidsexual person does feel sexual attraction and an urge toward someone, but has no wish to act on it. An aegosexual person, by that definition, feels arousal without attraction, so there is nothing to hold back. If “I’m attracted but I don’t want to do anything about it” sounds right, orchidsexual may fit better. Orchidsexual appeared only as a write-in in the 2022 survey, so no count exists.
Labels about change over time: aceflux
Aceflux: an orientation that moves
An aceflux person’s level of attraction shifts over time, between asexual, gray and allosexual. Allosexual simply means someone who regularly feels sexual attraction. One month the person may feel none, the next a fair amount, and the swing may follow no clear pattern. The label can stand alone or pair with a word for the genders the person is drawn to.
In the 2022 Ace Community Survey, 4.1% of ace respondents listed aceflux among their labels. In the 2021 survey, 5.8% said they had used it at some point. That makes it one of the smaller labels with its own tick box, but far from a fringe term.
How aceflux differs from gray-ace and abrosexual
Both gray-asexual and aceflux cover people who are sometimes attracted. The difference is shape over time. Gray describes attraction that is rare, faint or tied to specific circumstances, without saying the person’s orientation itself changes. Aceflux describes an identity that moves between asexual, gray and allosexual over time. Someone whose attraction shows up only in certain situations is usually gray. Someone who feels like a different orientation for a season, then shifts back, is closer to aceflux. The line is fuzzy, and some people use both words.
Abrosexual is the other near neighbour, and the axis is different again. An abrosexual person’s orientation changes in terms of which genders they are attracted to. For most aceflux people the genders stay the same, and only the strength of the pull changes. A related word, acespike, covers asexual people who get rare, short spikes of attraction rather than ongoing swings.
AVEN adds a note of caution. Most people’s sexuality goes up and down with age, health and life events without their orientation changing. A stressful year with no interest in sex is not the same as being aceflux. The label tends to fit people for whom the swings are a long-running pattern.
Where these labels come from, and how far to trust them

Coined online, counted by volunteer surveys
Almost every label on this page was coined by ace people talking to each other online, not by clinicians. Gray-a came out of AVEN forum threads. Reciprosexual was coined by a Tumblr user whose account no longer exists, on a date nobody recorded. Aceflux traces back to a Tumblr blog that has since been wiped. The definitions live on in community wikis that anyone can edit.
The numbers come from a similar place. Most counts on this page are from the Ace Community Survey, an annual online survey run by a small volunteer team since 2014. It is large: the 2024 edition kept 8,751 of 10,397 responses, from people in 96 countries. But it is a convenience sample, spread by sharing links through AVEN and social media. The survey team is blunt about the limit. Its respondents represent people in touch with ace communities, not ace people in general. The 2024 report adds that results lean toward people in English-language online spaces.
What the research can and cannot confirm
Population studies rarely ask about spectrum labels at all. The best-known estimate of asexuality comes from Anthony Bogaert’s 2004 analysis of a British national sample of more than 18,000 people. About 1% reported no sexual attraction to anyone. That figure counts the people who chose the no-attraction answer on a multiple-choice question about who they were attracted to. The survey had no options for spectrum labels, so it says nothing about how many people are gray, demisexual or aceflux.
Peer-reviewed work on the labels themselves is thin, but it exists for the biggest three. Copulsky and Hammack found that asexual, graysexual and demisexual respondents differed in measurable ways. Asexual respondents were the most likely to be aromantic, graysexual respondents the most likely to be grayromantic, and demisexual respondents the most likely to be demiromantic. So the core labels track real differences in experience. For reciprosexual, lithosexual, orchidsexual or aceflux, no comparable study turned up in the research for this guide.
Why microlabels help some people and frustrate others
For many people, a precise word ends a long search for what is wrong with them. Learning that others share a specific pattern can replace a sense of being broken with a sense of being different. AVEN frames its whole community around that shift, toward seeing asexuality as an orientation rather than a dysfunction.
The survey data also shows the limits. In 2022, 67.0% of asexual respondents said they identified very strongly with their label. Only 43.9% of demisexual and 29.9% of graysexual respondents said the same. Labels in the middle of the spectrum seem to fit more loosely.
Overlap is the other catch. When aces could tick every label that applied, the share choosing graysexual nearly doubled, from 10.5% to 19.0%. The survey team read that as a large overlap in identities under the ace umbrella. Some people find stacking labels useful. Others find that a long string of words explains less to a partner or doctor than one plain sentence about what they feel.
When a label stops fitting

How often ace labels change
Changing labels is normal on the ace spectrum, and the survey data shows it plainly. In the 2021 Ace Community Survey, 57.9% of ace respondents said they had once identified as straight. Some 31.5% had used demisexual at some point, while only 17.2% used it at the time of the survey. Graysexual followed the same pattern, with 25.2% ever and 17.4% currently. Many people pass through a spectrum label on the way somewhere else, sometimes toward plain asexual and sometimes away from it.
This is not unique to ace people. Christine Kaestle followed about 12,000 young Americans and found that changes in attraction, partners and identity were common into the late 20s. One pattern she identified, called “minimal sexual expression,” covered 6.5% of young men and 7% of young women. Later in life, change slows down. In a ten-year study of midlife adults, Mock and Eibach found that somewhat more than 2% reported a different orientation identity at the second wave.
A worked example: three words in five years
Consider a hypothetical person, Jordan. In their first year of college, Jordan calls themself straight, because that is the default and they date the opposite sex. Two years later, after reading about asexuality, they realise they have never felt drawn to anyone, and “asexual” fits. By their mid-twenties, Jordan notices faint attraction to one close friend and starts to say “gray-ace,” or perhaps “demisexual.”
None of these changes means Jordan was wrong before. Each word was the best description they had of what they had felt so far. The underlying experience may not have changed much at all. What changed was the vocabulary Jordan knew and the situations they had been in.
Ways to try a label without committing
Labels are easier to test when nothing rides on them. A few low-stakes approaches:
- Use the word privately first, in a journal or in your own head, and notice whether it brings relief or friction.
- Describe the experience instead of naming it, such as “I only feel attraction once I know someone likes me,” and see if a label follows.
- Read first-person accounts in ace forums and compare them with your own history, not with a checklist.
- Revisit the question after a year or after a big life change, since attraction and context both shift.
AVEN’s FAQ makes the same point directly: it is okay to change how you identify as you learn more about yourself.
FAQ: quick answers about ace spectrum labels
What is the difference between asexual and graysexual?
Asexual means feeling no sexual attraction, while graysexual means feeling it rarely, faintly or only in narrow circumstances. The boundary is soft. AVEN notes that many people in the gray zone still call themselves asexual because it is simpler to explain. Neither label is more valid, and either can be the right shorthand.
Can you be graysexual and demisexual at the same time?
Yes. Some people use gray as a broad umbrella for every ace identity that is not purely asexual, which would include demisexuality. Survey data points the same way. When aces could pick all the labels that fit, many chose more than one, and the survey team saw a large overlap between identities. Medical News Today also notes that some people shift between the two labels over time, which is a separate point from holding both at once.
What is fraysexuality?
Fraysexual describes someone who feels sexual attraction only toward people they lack an emotional bond with. As a bond forms, the attraction fades. That is why the community wiki calls it the opposite of demisexual, where attraction appears only once a bond exists. Another name for it is ignotasexual.
Is there an asexual spectrum test?
No test can decide where you sit on the spectrum. Medical News Today states that there is no test to determine whether someone is greysexual. Online quizzes can be useful prompts, because they ask questions you might not think to ask yourself. Treat the result as a starting point for reflection, not a verdict.
Do people on the ace spectrum have sex or relationships?
Some do and some do not, and the label alone will not tell you which. In the 2022 Ace Community Survey, 41.9% of ace respondents said their feelings about having sex depended strongly on circumstances. Respondents could pick more than one answer, so the groups overlap: 38.3% also or instead said they felt averse, and 12.4% said they felt favourable. Relationship status also varies by label. In 2024, 74.3% of asexual respondents were single, compared with 61.9% of graysexual and 56.5% of demisexual respondents.
Choosing a word for where you are now
Every label on the ace spectrum is an attempt to describe one part of attraction: how much, when, whether you want to act on it, or how it changes. Sorting them that way makes the choice easier. Ask which of those questions your experience is really about, and the shortlist gets short fast.
Hold whatever word you pick lightly. These terms come from community conversation and volunteer surveys, so they are useful tools rather than diagnoses. Many people use two at once, and many switch as they learn more about themselves. A label earns its place if it helps you understand yourself or explain yourself to someone else. If plain “asexual,” or a sentence about what you feel, does that job better, that works too. For more depth, our guides to asexuality and demisexuality pick up where this page leaves off.
