Taking on the Master role in [BDSM](https://gay-blog.tomrockets.com/en/bdsm-fetish-kink/ "BDSM") is not about posture. It is about being answerable for someone. That is the part most writing on this subject leaves out: it describes what a Master is allowed to do, and not what he answers for.

Answerability is what this comes down to. There is also a correction to make: this piece carried a claim about terminology for years that does not hold up. Which claim, and where it came from, is in the second section.

## What separates M/s from D/s, and where the sources disagree

The lowercase s in **M/s** stands for **[slave](https://gay-blog.tomrockets.com/en/servant-bdsm/ "slave")**. The international title contest for this relationship form was founded in 1990 and is called „International Master/slave“. Four independent scene glossaries resolve the abbreviation the same way, and none offers an alternative. Anyone resolving it differently has no source for it.

What separates M/s from **D/s** is harder than most guides admit. The abbreviation stands for dominance and submission. The English Wikipedia article on Master/slave draws the distinction through core values: where love is often the core value in D/s structures, service and obedience are often the core values in Master/slave structures. Yet the same encyclopedia lists M/s in its BDSM glossary as a subset of D/s, describing it as a relationship in which people „enter a D/s dynamic with a focus on service and obedience“. The **National Coalition for Sexual Freedom** in turn lists Master/slave as its own form alongside Total [Power Exchange](https://gay-blog.tomrockets.com/en/bdsm-total-power-exchange/ "Power Exchange"), 24/7 and Owner/property.

Three sources, three placements. There is no academic publication that systematically separates M/s from D/s. In practice that means the terms mark a tendency, not a border. Wikipedia does name the one point that holds across all sources: a slave is a specific type of submissive, but not every submissive is a slave. The counterpart perspective has its own piece on [the role of the BDSM slave](https://gay-blog.tomrockets.com/en/servant-bdsm/), and the range of dominant styles is laid out under [types of Doms](https://gay-blog.tomrockets.com/en/types-of-doms/).

M/s should not be confused with [Total Power Exchange](https://gay-blog.tomrockets.com/en/bdsm-total-power-exchange/), or TPE. That is a relationship form rather than a role label, and it describes the reach of what is handed over, not the titles of the people involved. A broader map of the field sits in the overview of [BDSM roles](https://gay-blog.tomrockets.com/en/bdsm-roles/).

## Serf is not a scene term

A claim in two parts stood here since 2023, and none of twelve scene glossaries checked supports it. First, that „serf“ is a new term from the USA for the role usually called slave. Second, that because of the historical connotation, „slave“ should be avoided in public.

The second part has a real basis. The first is wrong, and its origin can be traced precisely.

### Twelve glossaries, no match

**No scene glossary carries the term.** Twelve were checked. The English Wikipedia, the BDSM Wiki, the glossary of the National Coalition for Sexual Freedom (NCSF) and the German-language Datenschlag lexicon omit it, as do eight others. Wikipedia names **Owner/property** as the alternative to Master/slave.

**The only source is a German platform, and there it is a personal suggestion.** A [BDSM dating](https://gay-blog.tomrockets.com/en/dating-bdsm/ "BDSM dating") site founded in Munich in 2020 carries the sentence that also stood here. A second article on the same site shows where it came from: a blogger there suggests **„servant“** and describes that term as increasingly popular in US BDSM contexts. The author of the article then adds that „serf“ or „menial“ also seem suitable **to her**, noting that the latter is typically found in texts on medieval history.

That completes the chain. The statement about the USA referred to „servant“. „Serf“ was one German author’s own idea, explicitly marked as such. On its way into further blogs, including this one, it became a statement of fact about the American scene.

### What the scene actually proposes

**The debate itself is real.** Sinclair Sexsmith holds the International Master/slave 2020 and Northwest Master/slave 2019 titles. In July 2020 they published a statement announcing they would no longer use the terms „Master“ and „slave“. A follow-up piece collects suggestions from the scene: Maîtresse, Maîtriser, Dominate, Domina, Lady, Lord, Liege, Sovereign, plus a coined word built from the phonetics of M/s. A femdom magazine changed its editorial guide and replaces „slave“ with „property“, „owned and collared“ and „Owner“.

„Serf“ appears in none of those lists.

**And the historical comparison used to justify the term does not hold.** A serf was bound to a plot of land and could not be sold as a person, only together with the land. A slave was the property of a person. Those are two different forms of unfreedom, not synonyms. Choosing „serf“ to sidestep one history swaps it for another.

Anyone looking for an alternative has one that is documented: Owner/property. Anyone staying with Master/slave follows the majority of sources. What does not work is a term nobody outside a handful of German blogs uses.

## Who lives these roles, and what is actually known

The evidence amounts to two solid surveys with 19,307 and 902 participants. Neither measures M/s directly. Both measure BDSM as a whole.

**There is no population figure for M/s.** How many people run a Master/slave relationship has not been measured. What exists are shares within samples of people already practising BDSM, drawn from online surveys with self-selection. A 2023 study with 810 participants puts 1.6 % describing themselves as Master and 5.0 % as slave or property. Those are shares within a scene sample, not a frequency in the population.

**For BDSM in general there is exactly one representative figure.** An Australian telephone survey of 19,307 respondents found that 1.8 % of sexually active people had been involved in BDSM in the previous year, 2.2 % of men and 1.3 % of women. For this blog the next sentence of that survey matters more: this was more common among gay, lesbian and bisexual people. The data is from 2001 and 2002, so more than twenty years old, and it measures BDSM as a whole, not M/s.

The same survey clears away a common assumption. Respondents with BDSM experience were no more likely to have been coerced into sexual activity and no more likely to be unhappy or anxious. Men who had engaged in BDSM scored significantly lower on a scale of psychological distress than other men.

### What is known about dominants

Exactly one study has evaluated the dominant side separately. In 2013, Wismeijer and van Assen compared 902 BDSM practitioners with 434 control participants in the Journal of Sexual Medicine, by online questionnaire. The results came out mostly in favour of the BDSM group: less neurotic, more extraverted, more open to new experiences, more conscientious, less rejection sensitive, higher subjective well-being. One value came out less favourably, and it belongs in the picture: less agreeable.

Splitting by role, the authors wrote that where differences appeared, scores were generally more favourable for those with a dominant role than a submissive one. Reading that as a ranking between dominants and submissives misses the decisive line: **the least favourable scores belonged to the control group**, the people without BDSM experience. And the study carries the weakness of every online survey, it rests on self-selection.

Reading that as proof that dominants are the more stable people overstates it. What is supportable is narrower: the assumption that BDSM is a symptom did not hold up in either survey.

## The slave contract: what it cannot do

A scene contract is not a legally binding contract, and will not be enforced or recognized by any court. That is how briefly the NCSF answers the question of whether such a paper protects you. The earlier version claimed the opposite, namely that the slave would be released into freedom at the end of the contract period, provided the agreements had been honoured. That reads as though a contract binds until its term expires and as though release were a reward for good conduct.

The same source answers the second obvious question just as briefly. Does a long-term agreement such as one in a Master/slave relationship constitute blanket [consent](https://gay-blog.tomrockets.com/en/bdsm-consent/ "consent") for all BDSM activities? No. A person can withdraw consent at any time, regardless of the M/s contract.

That is not a question of interpretation, it is the foundation. Consent that cannot be withdrawn is not consent. The NCSF puts it more sharply in its statement on power exchange relationships. A contract that denies the right to withdraw consent may be problematic for the top in a legal setting. People cannot legally surrender that right. So the contract does not protect the Master. It exposes him, if it promises [too much](https://gay-blog.tomrockets.com/en/too-little-sex-too-much-sex/ "too much").

### What German law says, and what it does not

Under German law, section 138 of the Civil Code voids legal transactions that offend good morals. Section 228 of the Criminal Code makes bodily harm unlawful despite consent where the act offends good morals. What cannot be found is a decision measuring a slave contract against either provision. The Federal Court of Justice ruling on section 228 in an [SM](https://gay-blog.tomrockets.com/en/bdsm-fetish-kink/sm-pain-pleasure/ "SM") context concerned a case with fatal consequences and no contract document. The wording of a norm supports the norm, not its application to a particular contract.

For the anglophone world there is a thorough treatment. A note in the Harvard Law Review observes that one finds no litigation of BDSM contracts. That is striking, because breaches with no direct link to sex would warrant legal redress, such as a violated obligation to provide specified food and clothing. Where such contracts do show up in court documents, it says, it is generally not because the state is enforcing their promises. The state is then punishing the promisors under the aegis of criminal or tortious wrongdoing.

## What a contract is worth putting in writing

If the paper carries no legal weight, the question is what it is for. The Harvard note of 2014 names two uses and the NCSF a third. First: by requiring negotiation and drafting, contractual BDSM insists that its participants are aware and protective of their interests. Second: because such contracts ask parties to consider and communicate limits before committing to the relationship, they enable the assumption that a scene is the product of specific informed consent. Third, and this one comes from the NCSF. In a legal setting a written contract may help show the state of mind of the participants and which behaviours and responsibilities were agreed.

The Harvard note raises the criticism itself. Sexual desire, unlike contractual interest, is messy, fluid and fluctuating, near impossible to pin down at any given moment and less so in a negotiation deliberately set apart from the scene. It is precisely this notion of preset consent that makes BDSM objectionable to many who worry it renders the submissive partner a slave to their words rather than their desires. And those new or particularly credulous may enter an agreement on false terms, taking the contract’s appearance of definiteness at face value.

So a contract records a conversation, and it secures nothing. It does not replace ongoing communication, and it does not replace a [safeword](https://gay-blog.tomrockets.com/en/bdsm-consent/). Anyone wanting a more structured frame will find communication listed as its own item in the [4Cs](https://gay-blog.tomrockets.com/en/4cs-of-bdsm/), and the risk-oriented counterpart, [risk-aware consensual kink](https://gay-blog.tomrockets.com/en/safety-philosophy-rack/) or RACK, has its own piece.

One note on form that the earlier version got wrong: a document holding sexual preferences, limits and real names does not belong unprotected in a cloud service. If you keep it digitally, encrypt it.

A [collar](https://gay-blog.tomrockets.com/en/bdsm-collar/ "collar") or the Ring of O is often worn as a sign of belonging. The ring, however, comes from a novel and is not a general marker of an M/s relationship. What it means and what to watch for when wearing one is covered in the piece on the [BDSM collar](https://gay-blog.tomrockets.com/en/bdsm-collar/).

## What the leading role is responsible for

The obvious formula runs: responsibility lies with the Master. The main source on this subject contradicts that formula in the same passage where it appears to confirm it.

In its statement on consent, the NCSF writes that in the BDSM context it is the top or dominant who may be vulnerable to prosecution. An injured bottom is viewed in criminal law as the victim, not a party that commits a crime. For that reason the **legal** responsibilities and obligations fall on the top and not the bottom. The sentence that follows is the decisive one. The fact that the top has the legal obligations does not in any way detract from or lessen the equally important **ethical** responsibilities and obligations which the bottom shares in completely.

Legally one-sided, ethically shared. Anyone acting as Master carries the legal risk alone and the duty of care together with their partner.

For the line itself, the same organisation offers a distinction more usable than any list of rules. There is a difference between hurt and harm. Harm causes lasting damage, physical, mental or spiritual, and impairs the ability to function and enjoy life. Any hurt that is inflicted should ultimately bring fulfilment to those involved.

### How often limits are breached

Figures exist for this, and they need their reference group. In 2014 the NCSF surveyed 4,598 people via SurveyMonkey. Of the 4,503 who answered both relevant questions, 1,307 and therefore 29 % reported that their pre-negotiated limits had been violated or their safeword ignored. Broken down: 24.5 % named violated limits, 13.1 % an ignored safeword, and 8.5 % both.

By gender the distribution differs sharply, and for a gay blog that is the line that matters: **31 % of women reported a violation, against 13 % of men.** Nearly 36 % of all respondents said they had been touched without permission at a BDSM event.

By role, the survey reports tops were four to ten times less likely to experience a consent violation, most clearly where it was understood as part of the dynamic. That breakdown refers to the stated reasons, not to the overall rate.

Three limitations belong with these numbers. It was an online survey distributed through scene channels, so self-selection without a random sample. Nearly 90 % of respondents lived in the USA, almost 89 % described themselves as white, and the majority were women. Transferability to gay men is therefore not established.

### What happens after a session

The research here is thinner than the scene assumes. For dom drop, the crash on the dominant side, there is no physiological measurement. A theoretical paper from 2016 states outright that there is no research testing these ideas about the physiological profile of the immediate drop. The only hormone study in the field dates from 2009 and had 58 participants. It is not counter-evidence, because it measures something else. During the scenes cortisol rose for those who were bound, receiving stimulation and following orders. For those providing stimulation, orders or structure, no such rise appeared. Afterwards, participants whose scene had gone well showed less stress hormone and more closeness. Among those whose scene had gone poorly, closeness went down for some and up for others.

So it remains experiential knowledge, which is a legitimate reason to plan [aftercare against the drop](https://gay-blog.tomrockets.com/en/drop-bdsm/) for your own side as well. It is not a reason to claim a measured phenomenon.

Two further points the earlier version left open. Any altered state of mind affects the ability to consent legally, and consent obtained from someone who is impaired is, in the NCSF’s words, no consent at all. That covers alcohol and substances as much as deep [subspace](https://gay-blog.tomrockets.com/en/subspace-bdsm-achieving/ "subspace"), the altered state that intense stimulation can produce. A person may later report the wish but not the ability to withdraw. Warning signs from the other direction are collected under [red flags with subs](https://gay-blog.tomrockets.com/en/red-flags-with-subs/).

## Protocol and everyday life: how much role, and when

The earlier version listed four tiers here: occasional with low protocol, 24/7 with low, high at home and lower outside, and 24/7 with high. That classification is not documented in any of the sources checked. In the English Wikipedia’s BDSM glossary the terms „protocol“, „high protocol“ and „low protocol“ do not appear at all.

What is documented is narrower, and even there the sources disagree.

On **high protocol** they align: it applies for limited periods. The BDSM Wiki describes it as normally used for short periods or during longer punishments, with absolute and instantaneous obedience, without delay, hesitation or question. A guide from the leather scene names formal occasions for it: ceremonies, club nights, the play room, service time.

On **low protocol** the accounts diverge, and the disagreement is about whether anything applies at all. One scene guide calls it the most casual form, which for some people means no protocol at all. That same leather guide contradicts it: low protocol is the most commonly used form, it sets the rules of the household and is maintained around the clock unless the Master indicates otherwise. Low protocol, it says, does not mean rest, it means life. The BDSM Wiki sits between the two. It places low protocol in vanilla and informal situations, yet also describes it as a continuous reminder of service and its responsibilities, with casual behaviour permitted inside specific [boundaries](https://gay-blog.tomrockets.com/en/bdsm-limit-boundaries/ "boundaries").

All three accounts are scene self-reports rather than tested findings. Anyone looking for a classification to orient by will not find a binding one. What remains is the question itself, and it is the right one: how present should the role split be in everyday life, and where are there spaces in which it is suspended? Settling that in advance is worth more than any tier label.

Switching between [roles](https://gay-blog.tomrockets.com/en/dom-sub-two-very-special-roles/ "roles") does not make anyone half a Master. The [switch](https://gay-blog.tomrockets.com/en/switch-bdsm/) is its own role with its own piece, and dominance runs from strict to gentle, as the [soft Dom](https://gay-blog.tomrockets.com/en/soft-dom-definition/) shows.

## Address, titles and capitalisation

Forms of address turn up in almost every contract, and the conventions around them are less settled than they look.

Wikipedia notes that male Masters are usually referred to as „Master“. Whether female Masters are addressed as „Master“ or „Mistress“ may depend on whether they identify with the leather subculture or the BDSM path, or simply on preference.

The convention of capitalising terms for the dominant side and lowercasing those for the submissive side is documented several times over as scene practice, sometimes under the name „Slavese“. It is not binding, and it is contested within the scene by people who hold that standard grammar should apply. Two competing explanations of its origin circulate. One traces it to Old Guard leather guidelines, the other to chatrooms where capitalisation signalled roles. Neither is documented. Anyone using the convention does so as an agreement, not as a spelling rule.

## Where the terms come from

The formative period of gay leather subculture falls in the 1940s and 1950s. It grew mainly out of two groups: post-war California bikers in Los Angeles and pre-leather butch BDSM practitioners in New York City. Guy Baldwin held both the Mr National Leather Association and International Mr Leather titles in 1989. He calls „Old Guard“ a misnomer for the earliest set of habits that settled in the men’s leather community by the mid to late 1950s. Wikipedia records much debate over which traditions are the original ones, or whether the romanticised versions of leather history ever existed at all. Anyone invoking tradition here is invoking something contested.

## FAQ

### What does the lowercase s in M/s stand for?

Slave. None of the sources checked knows any other resolution. The international title contest founded in 1990, described by its current producer as the fourth oldest among international leather titles, carries the name „International Master/slave“. Anyone substituting „serf“ or „servant“ has no evidence for it. A mix-up is easy to see, though: in his „Leatherman’s Handbook“ of 1972, Larry Townsend used S and M for sadist and masochist, precisely not for slave and master.

### Is a slave contract legally binding?

No. According to the NCSF, no court enforces such a paper and none recognizes it. Regardless of what was agreed, consent can be withdrawn at any time. A contract that denies that right becomes a problem for the top when it matters, not a protection.

### What separates a Master from a Dom?

There is no settled answer, and that is the finding itself. The English Wikipedia names service and obedience as core values for M/s and love as often central in D/s, then lists M/s in its own glossary as a subset of D/s. The NCSF treats both as distinct forms. A systematic separation from the academic literature is missing. Only the direction is reliable: every slave counts as a submissive, and the reverse does not hold.

### Is serf a real BDSM term?

No. Twelve scene glossaries checked do not carry it, among them Wikipedia, the BDSM Wiki and the Datenschlag lexicon. The only source is a German BDSM platform, where it appears as the author’s personal suggestion alongside „menial“, with a note that the latter comes from medieval history writing. The claim about US origin referred, in that same source, to „servant“ and not to „serf“. In the actual alternatives proposed within the anglophone scene the term does not appear. Etymologically the detour leads straight back anyway: „serf“ derives from the Latin „servus“, meaning slave or servant.

### How many people live in a Master/slave relationship?

That has not been measured. For BDSM as a whole one representative figure exists. An Australian telephone survey of 19,307 respondents found 1.8 % of sexually active people in the previous year, 2.2 % among men, and more commonly among gay, lesbian and bisexual people. For M/s specifically there are only shares within self-selected scene samples, such as 1.6 % Master and 5.0 % slave in a survey of 810 people. A study of round-the-clock BDSM relationships states outright that their prevalence rates are unknown.
