Top means penetrating, bottom means receiving, vers means both. That is the whole basic meaning, and it refers to [anal sex](https://gay-blog.tomrockets.com/en/fucking-anal/ "anal sex") between men. Everything else is an add-on: how often, how much you enjoy it, how exclusively, and with what attitude.

The same two words carry a different meaning in [BDSM](https://gay-blog.tomrockets.com/en/bdsm-fetish-kink/ "BDSM"). There they say nothing about who penetrates whom, only about who performs an act and who receives it. Both meanings are old, both are documented, and this article keeps them apart. Sex first, BDSM further down.

## What a top is during sex

The top is the man who penetrates during anal sex. On its own, the word says nothing beyond that.

In particular, it says nothing about dominance. Those are two separate axes, and everyday usage collapses them constantly. A top can lead, and he can just as easily be led. Penetrating somebody tells you nothing about who sets the pace.

In practice, one thing hangs on the role more than anything else: the [erection](https://gay-blog.tomrockets.com/en/erection/ "erection") has to hold. That rarely gets discussed openly, even though it derails hookups. Nerves, alcohol, swapping a [condom](https://gay-blog.tomrockets.com/en/jerking-with-a-condom/ "condom") or simply the pressure to perform all push in the same direction. A top who can name that out loud has the better sex. For the technical side of the active role, we went through it properly in our guide to [top sex and the active role](https://gay-blog.tomrockets.com/en/top-sex-analsex/).

The second point is about responsibility. The top cannot feel what the bottom feels. He depends on being told, and he is the one who has to ask. Pace, angle and depth are decided by the man receiving.

That is where [consent](https://gay-blog.tomrockets.com/en/bdsm-consent/ "consent") actually sits. An arrangement holds for exactly as long as both men still want it, and not a moment longer. Talking about it does not kill the mood. It is the condition for the sex being any good in the first place.

## What a bottom is during sex

The bottom is the man who receives during anal sex.

Receiving means something different from being passive. That conflation is a stubborn one, and it holds up neither physically nor practically. The bottom often steers the encounter more than it looks: he sets how fast, how deep, in what position and when it stops. The fact that he is not the one thrusting changes none of that.

Physically the role asks a lot of you. The sphincter is muscle, and muscle answers tension with counter-pressure. Relaxation and [preparation](https://gay-blog.tomrockets.com/en/anal-sex-preparation/ "preparation") therefore do the work that force never will. Unlike a vagina, the rectum produces no lubrication of its own, which makes [lube](https://gay-blog.tomrockets.com/en/a-little-lube-sex-toy-material-guide/ "lube") a requirement. And the prostate sits a few centimetres inside along the front wall, which is why position decides whether anal sex feels good or merely feels like work.

Pain is not part of the exercise. Burning or a sharp sting is a signal that something is off. Usually there is too little lube, [too much](https://gay-blog.tomrockets.com/en/too-little-sex-too-much-sex/ "too much") pace or a bad angle. Pushing through the pain risks small tears.

How to get ready without turning it into a procedure is covered in our guide to [preparing for anal sex](https://gay-blog.tomrockets.com/en/anal-sex-preparation/). If penetration keeps staying tight, the piece on [bottom training](https://gay-blog.tomrockets.com/en/bottom-training-2/) is the one to read. And the practical groundwork for the receiving role sits in [bottom sex basics](https://gay-blog.tomrockets.com/en/bottom-sex-basics/).

## Versatile, vers and bttm: the shorthand

**Versatile**, shortened to **vers**, describes men with no fixed preference. They penetrate and they receive, depending on the partner, the situation or the mood. It is the third standard category in the research literature alongside top and bottom, and it turns up in dating profiles all the time.

Because a clean three-way split rarely matches reality, two in-between labels have settled in:

- **vers top** means both, leaning towards penetrating.
- **vers bottom** means both, leaning towards receiving.

Inside apps you will also meet the spelling **bttm**. It is nothing more than a short form of bottom and means the same thing.

Two older expressions may still cross your path: **pitcher** for the top and **catcher** for the bottom, both borrowed from baseball. They turn up mostly in older writing.

## Power bottom, service top and side

**Power bottom.** A bottom who actively steers the penetration and sets the terms. The sex therapist Jesse Kahn describes the role as active, confident and directive: a power bottom receives, but nothing simply happens to him. He sets pace, depth and position. Where the phrase came from cannot be established. The earliest written record sits in Steven Gregory Underwood’s 2003 book on gay anal eroticism; for anything earlier there is only guesswork.

**Service top.** The counterpart: a man who penetrates but takes his direction from the bottom. The Australian prevention organisation ACON sets the two side by side. A power bottom takes a dominant role during sex, a service top a submissive one: he follows the direction of the bottom he is servicing. In BDSM the phrase means something else, which is covered below.

**Side.** Men who have sex with men but not anal sex, neither penetrating nor receiving. The term goes back to the sex therapist Joe Kort, who introduced it in a 2013 piece for HuffPost. He puts his reasoning this way himself: a box has a bottom and a top, and it also has [sides](https://gay-blog.tomrockets.com/en/the-hottest-sex-of-my-life-without-anal/ "sides"). In a French survey of 8,755 participants, 2.9 per cent placed themselves there. Grindr has since added „side“ as its own position option.

Sides have sex. They just have it differently: oral, mutual [masturbation](https://gay-blog.tomrockets.com/en/is-masturbation-healthy/ "masturbation"), frottage, [fingering](https://gay-blog.tomrockets.com/en/fingering-among-gays/ "fingering"), toys. The idea that anal sex is the real gay sex is a convention.

## How many are what, and what the numbers are worth

The figures contradict each other, and they have to, since they measure different things.

**Self-label, five categories.** A US cohort of 4,802 [cisgender](https://gay-blog.tomrockets.com/en/cis-gender-affiliation/ "cisgender") men, reported in the Journal of Sex Research in 2025, allowed five answers. The split came out as bottom/vers 24 per cent, top/vers 22.5 per cent, versatile 20.3 per cent, top 17.2 per cent, bottom 15.8 per cent.

**Self-label, four categories.** A French online survey of 8,755 participants from 2020 asked without the hybrid options. It arrived at bottom 40.8 per cent, versatile 30.8 per cent, top 24.0 per cent and side 2.9 per cent.

**Behaviour rather than self-label.** The American EXPLORE study logged what men actually did across thirty months. For condomless anal sex, 63.0 per cent behaved versatilely, 16.7 per cent exclusively insertively and 9.6 per cent exclusively receptively. Counting every act of anal sex, the versatile share rose to 83.6 per cent.

That puts the range for versatile somewhere between 20.3 and 83.6 per cent. The difference sits in the question: self-image, desire and behaviour are three separate things.

A 2016 study with 429 participants measured exactly that gap. Bottoms behaved in line with their label 78.4 per cent of the time, tops 81.0 per cent, **versatiles only 49.0 per cent**. Anyone calling himself vers is therefore doing something else about half the time. The mirror finding is worth noting: not a single top reported behaviour that ran against his label.

**Nobody surveys self-identification in German-speaking Europe.** The European survey EMIS-2017 asked about the most recent sexual encounter instead, and 23,107 of its participants came from Germany alone. Anal sex featured in 74 per cent of all encounters. Measured against all encounters as well, 34 per cent were receptive only, 28 per cent insertive only and 12 per cent both. That measures one night, not a self-image. And a study of 302 adolescents aged 15 to 18 found a distribution that does not differ meaningfully from adult samples.

## Where the words come from

The earliest written record slang lexicography knows dates from 1960. A professional journal notes there that calling a man „tops“ means he will only take the active part in anal sex, while „tops or bottoms“ covers both. So the meaning starts out as a statement of position.

The other usage grew alongside it. Reference works place the terms in the gay leather culture of the fifties and the BDSM culture of the sixties. Through the seventies and eighties they moved into general gay usage and became a plain statement of role. Both traditions still run side by side, and that is where the confusion comes from.

## The same words in BDSM, a different meaning

In BDSM, top describes the man performing an act and bottom the man receiving it. Anal sex has nothing to do with it. Whoever flogs, ties or places a needle is the top, regardless of who penetrates whom or whether anyone penetrates at all. Somebody who takes both [roles](https://gay-blog.tomrockets.com/en/dom-sub-two-very-special-roles/ "roles") is called a **switch** there. It is the counterpart to vers, only on the other layer of meaning.

On top of that sits a second axis that gay sex vocabulary does not have: **dominant** and **submissive**. That pair describes who holds control, while top and bottom describe who acts and who receives.

This is why **service top** means something different in BDSM. There it describes somebody applying a technique on the bottom’s explicit instructions, and that somebody can be dominant at the same time. In an anal sex context the second axis is missing, so service top simply means he penetrates while the other man says how.

We took the [BDSM roles](https://gay-blog.tomrockets.com/en/bdsm-roles/ "BDSM roles") apart properly in our piece on [dom and sub](https://gay-blog.tomrockets.com/en/dom-sub-two-very-special-roles/).

## What your role says about you, and what it does not

The stock stereotype runs: tops are masculine and dominant, bottoms are soft and submissive. The data does not support it.

The French survey of 8,755 participants asked about five traits commonly coded as feminine: caring, comforting, empathy, intuition and verbal ability. On all five, **bottoms scored lowest** and versatiles highest. On risk-taking, bottoms came out above tops, 27.6 against 22.7 per cent. The authors write that their data counter the social assumption that bottoms hold a psychological make-up traditionally associated with femininity. These figures come from a conference abstract rather than a peer-reviewed full paper, which limits how much weight they can carry.

On the other side there is a measurable but very small effect. In a study of 429 participants, tops rated themselves as more masculine than bottoms did, with versatiles in between. The effects explain only a few per cent of the variation, which makes them useful for statements about groups and useless for statements about a person.

A study of 282 participants concluded that men learn their label over roughly fifteen years. The role forms out of experience. Penis size worked only indirectly: men who thought of themselves as smaller more often felt apprehensive about penetrating and settled on a bottom label. The label was directly predicted by just two things, namely how much pleasure a man takes in receiving and how much sexual control matters to him.

## Can you tell whether a man is a top or a bottom

Somebody has actually studied this, and the answer is: barely.

In a 2013 study, participants were shown 200 profile photos, a hundred each of men who identified as tops and as bottoms. The hit rate landed just above chance. Broken down it looks worse: tops were identified correctly 64.6 per cent of the time, **bottoms only 38.8 per cent**, which is worse than guessing. The reason is a bias. When unsure, the judges said top, and what they were really rating was perceived masculinity.

There is also a methodological catch the lead author raises himself: those 200 photos were rated by just 23 people. A follow-up with 121 judges produced the same pattern and the same bias.

So people believe they can see it. They land marginally above chance and err systematically in one direction. Reading a role off a face is guesswork.

## What your role means for risk

Here the question of role genuinely matters, and it matters a lot.

A systematic review by the US health agency CDC, published in 2014, pooled the per-act probability of acquiring HIV. The reference point matters: these are acts with a partner whose HIV infection is untreated, without a condom and without PrEP.

- **receptive anal sex: 138 transmissions per 10,000 exposures**, or 1.38 per cent
- **insertive anal sex: 11 per 10,000**, or 0.11 per cent

That leaves roughly a twelvefold difference between the two roles. The individual studies behind the figure vary considerably, from 82 to 143 per 10,000 depending on the cohort, and one modelling exercise gave a range of 50 to 300. The order of magnitude holds; the precise number does not.

The second finding in the same review matters just as much: **a condom plus effective HIV treatment in the partner cuts the risk by 99.2 per cent together.** PrEP changes the arithmetic again. How that works is covered in our piece on [PrEP](https://gay-blog.tomrockets.com/en/hiv-prep/).

**Being a top is still not protection.** Prevention services are explicit that the insertive partner carries a risk too: the mucous membranes on the inner foreskin, at the urethra and around the [frenulum](https://gay-blog.tomrockets.com/en/frenulum-2/ "frenulum") can take up HIV. The same sources stress that every figure quoted here is a statistical value. One man can acquire HIV from a single exposure while another has many without consequence.

With other [sexually transmitted infections](https://gay-blog.tomrockets.com/en/health-en/sexually-transmitted-infections/ "sexually transmitted infections") the picture blurs further. A Seattle study tested 292 men who do **not** have receptive anal sex for rectal infections. **14.1 per cent came back positive** for [chlamydia](https://gay-blog.tomrockets.com/en/chlamydia-infection/ "chlamydia") or [gonorrhoea](https://gay-blog.tomrockets.com/en/gonorrhoea-symptoms/ "gonorrhoea"). [Rimming](https://gay-blog.tomrockets.com/en/rimming-sex/ "Rimming") and play around the anus come into question as routes of transmission. An older San Francisco survey found around 85 per cent of rectal infections running without symptoms. A Dutch study of 9,549 participants found 85.6 per cent of rectal infections occurring on their own, with no urethral infection alongside. A urine test would have missed every one of them.

Rectal swabs therefore belong in your testing routine even if you think of yourself as a top. More on that in our overview of [STIs in gay men](https://gay-blog.tomrockets.com/en/sti-in-gays/).

## How to work out what fits you

The fastest route is trying things, and doing it without any obligation to wear a label afterwards.

Three things help more than any amount of self-examination. Say beforehand what you want and what you do not want right now; one sentence will do. Start with whatever feels obvious rather than whatever you think is expected. And treat the result as provisional. The studies point the same way: the label forms over years, and a sizeable share of men behave differently from how they describe themselves anyway.

If you already know both and want to know how switching works inside a relationship, we covered that in the piece on [role reversal in bed](https://gay-blog.tomrockets.com/en/gay-role-reversal/). And if you want to start further back, our guide to [having anal sex in the first place](https://gay-blog.tomrockets.com/en/i-want-anal-sex/) covers everything that comes before the question of role.

A role stays a preference. It is not a character trait and certainly not a ranking. Turning it into a verdict on somebody says more about you than about him.

## FAQ

### What does top and bottom mean in sex?

Top describes the man who penetrates during anal sex, bottom the man who receives. Both words describe a position and nothing more. They say nothing about character, masculinity or who is in control.

### What does vers mean?

Vers is short for versatile and describes men who do both, penetrating and receiving. Alongside it sit vers top and vers bottom for a preference with a lean. Depending on whether a study asks about self-image or about actual behaviour, somewhere between 20.3 and 83.6 per cent of men fall into this group.

### What is a power bottom?

A power bottom receives while steering the encounter: pace, depth and position. The sex therapist Jesse Kahn describes the role as active and directive. Receiving and being passive are two different things, and the power bottom is the clearest example of that.

### Can I change my role?

Yes, and plenty of men do. A study of 429 participants found that men who describe themselves as versatile behave accordingly only about half the time. Another concluded that a man’s label takes shape over roughly fifteen years. It is a snapshot rather than a fixed setting.

### Is bottoming riskier than topping?

The reference point is anal sex without a condom and without PrEP, with a partner whose HIV infection is untreated. On that basis the risk sits at 138 transmissions per 10,000 exposures for the receptive role and 11 for the insertive one. That is roughly a factor of twelve. A condom plus effective treatment in the partner brings the risk down by 99.2 per cent together, and PrEP shifts the arithmetic again. Topping is no free pass either: the insertive partner can acquire HIV as well, and rectal infections turn up even in men who never bottom.

### What does bttm mean?

Bttm is the short spelling of bottom used in dating profiles. It means the same thing and carries no separate sense of its own.
