PI-42 / Field note
Talking about desire
English offers two registers for this subject: a clinical one that sounds like a consultation and a crude one that sounds like a joke. Neither works in a bedroom, and the gap between them is where a great many conversations die.
Try to describe, out loud and to another person, exactly what you want done. Most people find they reach for a word, reject it as too medical, reach for another, reject it as too coarse, and settle for a gesture or a vague noise. The difficulty is not embarrassment. It is that the language has a hole in the middle.
Where the hole came from
The clinical register was built for examination rooms, where precision matters and warmth does not. The crude register was built for jokes, insults and boasting, where impact matters and precision does not. There has never been much need for a third register, because the situations that require it are private and therefore leave no written record for the language to standardise around.
Every couple that solves this solves it locally and privately, and none of those solutions propagate. So each pair starts from nothing, which is why the problem feels personal when it is structural.
Where the gap shows
The gap shows up as vagueness. That was nice carries almost no information. Slower carries a great deal. In the absence of usable words, people substitute two things: guessing, which is slow and often wrong, and after-the-fact praise, which is kind and entirely useless as a signal.
The result is that a lot of sex proceeds on assumptions formed early and never revised, and two people can spend years being politely mistaken about each other.
Building a private language
The practical answer is to stop hunting for the correct public words and to build a small private set instead. Three properties make it work.
It should be short. Two or three words maximum, since anything longer breaks the state it is trying to adjust. Slower. Stay there. Left a bit.
It should be present tense and about the action rather than about the person. Harder now is an instruction. You are not doing it hard enough is a review, and reviews land badly at close range.
And it should be agreed outside the situation it is for. A vocabulary negotiated at a kitchen table, fully dressed, with nothing at stake, is far easier to establish than one attempted in the middle of a session where every word carries weight.
Naming the parts
A specific version of the problem: many people have no comfortable word for their own anatomy. The clinical terms feel like a textbook and the slang feels borrowed from someone else's mouth. This matters more than it sounds, because a body part with no sayable name is difficult to make requests about.
There is no general solution, only a local one: pick something, use it a few times until it stops being conspicuous, and accept that the first several uses will feel artificial. Artificial is a stage, not a verdict. The precise terms are set out in the glossary for anyone who wants the accurate version to start from.
Timing
The worst moments for a substantive conversation about sex are immediately before, during, and immediately after. Before, it reads as a condition. During, it interrupts. After, it reads as a verdict on what just happened, and the other person will hear a review no matter how it is phrased.
The good moments are ordinary ones: walking, driving, cooking, doing something else with hands busy and eye contact optional. Conversations of this kind go better sideways than face on.
Asking rather than reporting
A question with a real answer beats an invitation to reassure. Is there anything you have wanted to try and not mentioned produces something. Was that good produces yes, every time, from everyone, regardless of the truth.
The same applies to the most useful question in the category, which is what someone does when alone. It is specific, it is answerable, and it produces information no amount of observation would supply. The method in body mapping exists partly to give a person something concrete to say when that question is asked.
What it buys
Not romance and not technique. Accuracy. Two people working from an accurate picture of each other will do better with modest skill than two people with excellent technique working from assumptions made years ago. The wider ground is in the together region.
