Power bottom: what the term means, and why it is not a contradiction
A power bottom is the receptive partner in sex who is also the one running it. The term comes from gay male vocabulary, where top and bottom describe who is penetrating and who is being penetrated, and it exists because those two words kept getting mistaken for a description of who is in charge.
What the word actually says
Top and bottom describe a physical position. That is the entire content of the pair. They say nothing about who decided, who is setting the pace, or who wants what.
In practice they get read as if they did. Bottom gets heard as passive, top as active, and a whole set of assumptions arrives that nobody agreed to. Power bottom exists to break that reading in one word: the person being penetrated is directing the encounter.
It is not a paradox and it is not a joke, although it is often used as one. It is a correction.
Where it came from
The vocabulary is gay male and comes out of the second half of the twentieth century, along with the rest of the top and bottom shorthand. Power bottom is later, and it arrived as community slang rather than from any single source, which is why every definition of it differs slightly.
The term has since travelled well outside the community that made it. It is used in straight contexts, in queer contexts of every configuration, and as a general figure of speech about anyone who appears to be in the subordinate position and is obviously running things. That travel is worth knowing about, because the further it goes the looser it gets.
The related terms, which are easy to mix up
Total bottom
Someone who is exclusively receptive and wants to be led as well. This is the reading that power bottom exists to distinguish itself from.
Service top
The inverse. The penetrating partner who is there to provide what the other person wants, following rather than directing. A service top and a power bottom are an extremely common pairing, and the reason is obvious once the words are separated from the assumptions.
Power top
The one the assumptions already describe: penetrating and directing. The word exists mostly for symmetry.
Versatile
Someone who does both, depending. Versatile is about position; power bottom is about who is steering. A person can be both.
Position and authority are two different axes
This is the useful part, and it generalises well beyond the vocabulary it came from.
One axis is physical: who is doing what to whom. The other is about control: who is deciding, setting the pace, saying when. They are independent. Every combination exists and each one is somebody's favourite.
Most confusion about roles, in any configuration and any orientation, comes from collapsing those two axes into one. The entry on dominance and the entry on submission describe the second axis in the language the rest of this site uses, and they deliberately say nothing about position.
A power bottom may or may not be dominant in any broader sense. Plenty are, in the encounter and nowhere else. Some are submissive in every other respect and still run this part. The term describes what happens in the room, not a personality.
How it actually reads in a room
Concretely: setting the rhythm rather than receiving it. Saying what happens next. Changing the position because they want a different one. Being the person who is enthusiastic and specific rather than the person being figured out.
The physical version most people picture is riding, because it is the position where the receptive partner has the most control of pace. That is the image, but it is not the definition, and the definition survives in positions where it does not apply.
The thing it always involves is an appetite stated rather than waited for. If you had to reduce it to one sentence: a power bottom asks.
The part fiction does better than life
Written sex has an old habit of giving all the interiority to whoever is on top, and all the reaction to whoever is underneath. The receptive partner gets described rather than heard from. It happens in straight and queer writing equally, and it is a habit rather than a choice.
A power bottom breaks it by construction. The person being penetrated is the one with the plan, so the natural viewpoint is theirs, and the prose has to carry appetite rather than just sensation.
Written down you can also do the thing real life makes awkward: let the pace be argued over. Two people negotiating rhythm without stopping is a very specific pleasure to read and almost impossible to film.
Say it in your own words in the special instructions. Something like: he is underneath and he is running it, the other one is glad to be told, and neither of them treats this as surprising. That is a different story from the same setup written as a reversal.

The entry on dominance and the entry on submission are the other axis, and they are worth reading alongside this precisely because they do not mention position.
The guide to soft dominance is the closest relative: it also exists to separate authority from the manner people assume goes with it.
The entry on rough covers intensity, which is a third axis again and gets confused with both of the others.

Privacy, since this one is specific
A story built around a particular role says something about the person who asked for it. Your stories are encrypted at rest. We can read them to write them. Nobody else can read them. The privacy guide sets out what that covers and what it does not.
Every character in a sexual context is an adult. That one is not a setting.
