# Erotic spanking and how it differs from discipline

> Spanking as part of sex and spanking as its own event share a word and almost nothing else. What separates them, and why people ask for one and get the other.

- Audience: consenting adults over 18 only. Everything on this site concerns consenting adults over 18.

Two adults use the same word and mean two unrelated activities. One is a few smacks during sex. The other is a formal event with a start and a finish, and often nothing sexual in it anywhere. Asking for the second and being handed the first is one of the commonest disappointments in this whole subject, and almost nobody has the sentence to fix it.

## In short

- Between consenting adults over 18, erotic spanking sits inside sex. A session is its own event, with edges, and is often entirely non-sexual.
- A session is normally far heavier. Bedroom spanking has arousal doing much of the analgesic work, which a hairbrush from cold does not.
- Agreeing to be spanked is not agreeing to what follows it. Decide beforehand whether it ends in sex, and who may raise it if it does not.
- Arousal arriving during a non-sexual session is common and settles nothing on its own. See [arousal and who can hide it](https://consensualspanking.co.uk/guide/arousal-and-who-can-hide-it/).

Two adults, both over 18, and a word that covers two activities with very little in common. One is spanking as part of sex, folded into what a couple already do in bed. The other is spanking as an event in its own right, with a beginning and a deliberate end, which may involve no sexual contact whatsoever and in a great many arrangements does not.

People ask for one and are given the other all the time. The person it happens to usually cannot work out how to say what went wrong, because every available phrasing sounds like a complaint about their partner.

## The bedroom version

This is the one most people have met, because it is the version that turns up in almost everything written about sex. Hand, usually. A few swats, sometimes a couple of dozen, no number agreed and nobody counting. There is no warm-up, because arousal is doing that job, and it stops when the two of you move on. It is lighter than people who have only read about spanking tend to picture.

## The session version

The other one has edges. Somebody says a sentence that begins it. There is a position chosen in advance and then held, a hand or an implement, a length of time, frequently a number. It ends on a stated point rather than drifting, and then two people sit down with a cup of tea and the evening carries on.

Whether any of that is sexual is a separate question, and the answer covers the whole range, from entirely non-sexual through charged but hands-off to part of a sexual encounter. See [does spanking have to be sexual](https://consensualspanking.co.uk/guide/is-it-sexual/).

## Why the two get confused

Same word, same part of the body. If the only version you have encountered is the bedroom one, assuming the other is a longer or firmer edition of it is a reasonable guess. It is also wrong in a way that is hard to spot from outside.

The trouble that follows is specific and I hear about it constantly. Somebody asks for a proper spanking. Her partner is delighted, and willing, and about a minute in he has turned it into foreplay, because it is the only version he has met and because wanting her feels like the compliment on offer.

What she wanted was twenty minutes of being in charge of nothing. The moment it becomes sex that has gone, and she has to explain the loss without sounding like she is turning him down.

It runs the other way too, and gets discussed far less. Somebody who enjoys a few smacks in bed agrees to try a session and finds the formality unsettling: being told to stand up and wait while an implement is fetched from a drawer, and a partner who has gone quiet and businesslike. That atmosphere delights some people and alarms others. Wanting only the bedroom version is an ordinary place to land.

## What actually differs

| Difference | In bed | As its own event |
| --- | --- | --- |
| Length | A minute or two, absorbed into everything else | Twenty minutes to well over an hour, the spanking only part of it |
| Warm-up | Rarely deliberate. Arousal covers it | Deliberate and unhurried, building from light |
| Position | Whatever the bed allows | Agreed in advance and held. Over the knee, over a chair, bent over a table, standing against a wall |
| Counting | Almost never | Common. A number set beforehand, sometimes counted aloud |
| Clothes | Already off, or coming off as part of the sex | Often stay on. When they come off it is a specific moment with meaning attached |
| How it ends | Drifts into whatever comes next | Ends on a marked point. A last stroke, or a time agreed at the start |
| Aftercare | The ordinary closeness that follows sex | Planned. Water, a blanket, a conversation, and knowing how you are getting home |

## Consent, which is the part that matters

Agreeing to be spanked is not agreeing to what comes after it. That principle is set out on [does spanking have to be sexual](https://consensualspanking.co.uk/guide/is-it-sexual/) and I will not repeat it here. What this page adds is that asking "is this sexual?" is too coarse to settle anything on its own. Four things need answers before anybody is undressed:

- whether this ends in sex, decided in advance rather than in the moment
- whether either of you may raise it afterwards, or only one of you
- what happens if one of you wants to and the other does not
- whether the answer holds every time, or gets set again for each session

The third one catches people. "We will see how we feel" sounds relaxed and generous, and in practice it hands the decision to whichever of you has more nerve at that moment. Twenty minutes after a hard session, that is rarely the person who has just been over the knee. Settle it while you are both dressed. There is a method for the whole conversation on [negotiation](https://consensualspanking.co.uk/guide/negotiation/).

## When arousal turns up uninvited

It does, in sessions that were agreed as non-sexual, and it does so often. It settles nothing. A body responding to adrenaline, a held position and somebody else deciding the pace is not a body casting a vote about what should happen next. The rule I use is that arousal is information about a nervous system and not an instruction to anyone in the room.

Both of you should know that beforehand. The awkward version is the one where nobody expected it and each assumes it has to be acknowledged. More on it, including which of you can conceal it and which cannot, on [arousal, and who can hide it](https://consensualspanking.co.uk/guide/arousal-and-who-can-hide-it/).

## Intensity, which people badly underestimate

A session is heavier. Not slightly. A hand during sex, with arousal doing much of the analgesic work and adrenaline already up, sits somewhere entirely different from a hairbrush on cold skin with somebody counting to thirty.

I got this wrong once. She had done the bedroom version for years, told me she had a high pain threshold, and I believed her. We were keen to get on with it, so I warmed up for about ninety seconds and reached for a paddle.

Nothing was damaged. She went quiet for the rest of the evening and told me a week later that she had spent the whole session waiting for it to be over and could not find a way to say so. I had skipped the part that makes the rest bearable, and the cost showed up in her mood rather than on her skin.

So now I take the warm-up well past the point where it feels necessary with anybody new, and when somebody tells me they have done this before I ask which version they mean. See [warm-up](https://consensualspanking.co.uk/guide/warm-up/) and [does it hurt](https://consensualspanking.co.uk/guide/does-it-hurt/).

## Doing both with the same person

Plenty of couples do. It is the easiest arrangement to manage and the easiest to blur, since the same two people in the same flat are doing both. What seems to work is a marker neither of you can miss:

- a different room, so the kitchen chair means one thing and the bedroom means another
- a different implement, kept somewhere specific, so fetching it announces the change
- a form of words that starts it, and a different one that ends it
- a different time of day, which sounds trivial and works better than it should

I am genuinely not sure how much of that is the marker doing the work and how much is that couples who bother to set one up are couples who talk about this properly. My guess is mostly the second. They still seem to help, so I keep recommending them with the caveat attached.

> **Where to say it.** If you keep asking for a session and keep getting foreplay, the change that works is usually about where you say it rather than how. Try a Sunday afternoon at a table with your clothes on. The same sentence at eleven at night arrives as a review of the last twenty minutes. At a kitchen table it arrives as a request.

## Common questions

### What is the difference between erotic spanking and disciplinary spanking?

Erotic spanking happens inside sex. It is usually a hand, a handful of swats, no set number and no warm-up, and it stops when the mood moves on. A disciplinary or session spanking is an event with its own beginning and end: an agreed position, often an implement, often a count, and a deliberate finish. In a great many arrangements the second involves no sexual contact at all, and it is normally much heavier than the first.

### Does erotic spanking always lead to sex?

No, and the answer is a decision the two of you make rather than a property of the activity. Some couples fold spanking into sex every time. Others keep sessions completely separate and would find it jarring if one turned into the other. Agreeing which of those you are doing, before anyone is undressed, prevents almost every version of this going wrong.

### How do I ask for a spanking that does not turn into sex?

Say it somewhere other than the bedroom and at a time when neither of you is aroused, because the same sentence lands as a request at a kitchen table and as a review at eleven at night. Name the two things separately: that you like what you already do in bed, and that this is a different thing you want kept apart from it. Then agree in advance what happens if one of you wants it to become sexual afterwards and the other does not.
