Ask people who reads adult illustration about women in relationships with women and most will answer confidently and, on the available evidence, incorrectly. The assumption has been stable for decades and it has shaped an enormous amount of published work, which makes it worth examining even though the data available is imperfect.

The stakes are practical rather than political. An artist who is wrong about who is reading makes different framing decisions, writes different dialogue, and ends up with work optimised for an audience that is smaller than the one actually available.

Where the assumption came from

Commercial publishing in this area was for a long time organised around one presumed reader, and everything from cover design to marketing to shelf placement followed. Artists learned the conventions from that published work, which encoded the assumption, and passed it on. Nobody had to believe it for it to persist; they only had to copy what already existed.

This is the same self-reinforcing process described in the piece on the default body, and it produces the same result: a convention that feels like a fact because everything visible agrees with it.

What the evidence suggests

Platform demographics, reader surveys, convention attendance and subscription data all point in a consistent direction: a substantially more mixed readership than the assumption allows, including a large proportion of women, and a notable share of readers who came for the relationship writing rather than for explicit content specifically.

None of these sources is authoritative on its own. Self-reported surveys skew, platform data is partial and often withheld, and event attendance reflects who can travel. But they agree with each other more than any of them agrees with the traditional assumption, which is the relevant point.

How the wrong assumption shapes work

It shows up in framing that treats one character as a viewpoint and the other as scenery, in dialogue written to be overheard rather than exchanged, and in relationships that exist entirely in the explicit scenes and nowhere else. Each of these is a reasonable choice for one imagined reader and a poor one for the readership that is actually there.

It also shows in what gets cut when a project runs short of time. Under the traditional assumption, the relationship material is the first casualty, and it is frequently the part readers were most attached to. That is an expensive mistake to make on the basis of an unexamined belief.

Writing for the audience you have

Practically this means treating both characters as viewpoints, writing dialogue that makes sense between them rather than for a listener, and giving the relationship material outside the explicit scenes room to exist. None of this reduces the appeal of the explicit work; it usually increases it, since stakes make scenes matter.

The structural version of this argument is in the piece on choreography, where mutual attention makes a scene read as shared. The commercial version is that readers who feel addressed rather than overlooked subscribe, and subscription is where the income is, as described in the piece on where the money comes from.

The audience that arrived late

Something else has changed since the assumption formed. Distribution moved from print shops and specialist shelves to platforms anybody can reach, and the readers who were previously invisible because they had no comfortable way to buy anything became visible almost overnight. A great deal of what looks like a shift in taste is really a shift in access.

That matters for anyone estimating a market, because historical sales figures describe who could buy rather than who wanted to. Treating those figures as a description of demand builds a plan on a measurement of a constraint that no longer applies, which is a subtle way to be confidently wrong about a whole readership.

Finding out rather than assuming

Artists can check cheaply. Ask on a mailing list. Read what people write when they share the work. Look at which posts convert to support and which merely get attention. This is unglamorous audience research and it beats inherited assumptions comprehensively, because it describes your readers rather than an imagined average.

Whatever the audience, the standards do not move: fictional, unmistakably adult characters, as set out in the reader agreement. Corrections and better data are always welcome through the letters page.
