Butterfly Wings, and Why One Is Almost Always Bigger

Part the outer lips gently and the inner pair spread into two thin, smooth shapes that people have been comparing to wings for as long as anyone has bothered to describe this anatomy.

One of them is bigger than the other.

That is the sentence that sends women to search engines at one in the morning, so it is worth putting the reassurance before everything else: asymmetry here is the rule, not the exception, in the same undramatic way that your feet are different sizes and your face is not a mirror of itself. A vulva with two perfectly matched halves would be the unusual finding.

The shape

Inner labia that are relatively large but thin and smooth, with little bulk to them, and that spread outward into a broad wing shape rather than hanging in folds. Frequently one side is noticeably longer or wider than the other. A hood that is slight to average, covering the clitoris partly rather than completely, so the glans is often findable without much searching.

In the framework this article is about, that spread-wing shape is the single most noticeable feature of the type at the North of the wheel, and the book names the size difference between the two sides as part of the ordinary description rather than as a flaw. Whatever else you make of the system, a taxonomy that writes asymmetry into the definition of a normal type is doing something more honest than a surgical before-and-after.

The measurement the book argues with itself about

The framework's own identifying measurement is the distance between the clitoris and the vaginal opening, taken by laying your fingers together horizontally under the clitoris and counting how many fit before the entrance. It is a quick thing to do, it needs no equipment, and it produces a number that is genuinely more informative than a photograph.

The book gives two different answers for this type.

Where it sets out the method, at the opening of the chapter, it anchors the scale with roughly one finger at the short end and roughly four at the long end, and puts the North at the long end. Later, in the type's own summary block, it says one to two fingers. Both sentences are in the same chapter.

This site's quiz follows the chapter opening, because that is where the book presents the measurement as a method, and because it is the reading that makes the rest of the chapter hold together. But you should know the contradiction is there, and that nobody has resolved it, and that a system whose primary measurement disagrees with itself by two finger widths is not a precision instrument. If you want to run the measurement yourself, the members' quiz at /tools/labia-quiz does it without a photograph of anything.

The claim that stays in the book's voice

One assertion in this section needs flagging rather than repeating.

The book states that Wolf Women frequently have tipped uteruses, and that they often feel as though they need to urinate during sex because of pressure against the bladder. That is the book's claim, and it offers nothing to support it.

For context rather than diagnosis: a uterus that tilts backwards instead of forwards is a recognised, ordinary variation, and in most women it causes no trouble at all. What does not exist is any evidence connecting it to the external shape of the labia. You cannot infer the position of a uterus from the appearance of a vulva, and the book does not explain how it arrived at the link.

Anything in that territory is a question for a doctor rather than a naming system, and this site is not offering one.

What Charles claims about the women

The framework is one woman's system: nine vulva types on a wheel of eight compass directions and a centre, set out by Amara Charles in the book credited below and taught in her workshops since the 1990s. Four of the nine are cardinal points described in full with measurements, and this type sits at the North, which the book calls the place of the mind.

That placement does the explanatory work. Because the North is the mind, Charles describes Wolf Women as highly intelligent, reflective, verbally quick and often funny, women for whom conversation is a genuine part of arousal rather than a preliminary to it. She describes them as loyal and pack-minded, valuing independence in stretches. The weakness she attributes to the type is overthinking: getting caught in their own heads until the cleverness works against them. Her summary line for the North's sexual temperament reads: intelligent, insightful, wild, creative and intense. She also reports a claim she says Wolf Women commonly make, that they are more interested in sex around their period, and links it to the moon.

All of that is her assertion. Her stated method on these pages is anecdotal, drawn from years of conversation in her workshops rather than from data of any kind, and the book itself says the anatomy and the qualities can come apart, so a woman may have this shape and none of the described temperament.

One passage in this section is better than the rest and deserves reporting properly. Charles writes that this type is noisy during sex, then immediately notes that many women who identify as Wolf Women say they are quiet, attributes that to never having been given permission to make noise, and finishes by saying that the sounds a woman makes are entirely her own business and what matters is that she feels free. That is a framework correcting itself in public, and it is the right instinct.

One framework among many

There is no research behind these nine types. No clinician uses them, no textbook contains them, and nothing here has been measured against a population. It is one author's system, and it should be held the way you would hold any system that names things without testing them.

The part of it that survives contact with reality is the plain description: thin wing-shaped inner labia, commonly uneven, are an ordinary way for a body to be built. That is true with or without the wheel. The fuller range is set out in Are My Labia Normal? The Honest Answer.

And the book's own instruction is to read and decide for yourself. It says a type cannot simply be seen and named, which means nobody gets to hand you one, including this site.
