The kinks romance and erotica writers use most are power exchange (dom/sub, praise, degradation, daddy kink), restraint (bondage, rope, collars), impact play and spanking, primal play, consensual non-consent (CNC), watching and being watched, sensation play such as overstimulation and orgasm denial, pet play, size kink and breeding kink. The table below covers 20 of them, each with how many people search for it each month in the US and what the scene has to show on the page to work. After it come the rules shops and sites apply to kink, and which AI models will write a kink scene at all.
The page is for writing them, not for a personal checklist. It stays non-explicit, and every character in it is an adult.
The kinks list: 20 kinks, searches and what the page needs
Searches are Google Keyword Planner's average monthly US searches for the kink's own name, pulled on 9 November 2026. Keyword Planner hides or zeroes many sexual queries, so treat a small number as a floor.
| kink | US searches / month | what it is | what the scene has to show |
|---|---|---|---|
| Shibari (rope bondage) | 110,000 (mostly the art and photography, not fiction) | Japanese-style decorative rope tying | Time and patience on the page; the tying is the scene |
| Breeding kink | 27,100 | Arousal at the idea of getting pregnant or getting someone pregnant | Both want it, said out loud; the fantasy is the point, so the talk carries the scene |
| CNC (consensual non-consent) | 22,200 ("cnc kink") + 6,600 ("consensual non consent") | An agreed scene played as if one partner were unwilling | The agreement before the scene, on the page or clearly behind it, and a way out both know |
| Praise kink | 18,100 | Being told you're good, beautiful, doing well | Specific praise, in the speaker's voice; what it does to the one hearing it |
| Pet play | 12,100 | One partner takes the role of a pet (a kitten, a puppy) and the other the owner | The roles agreed as roles; who decides when they end |
| Impact play | 12,100 (spanking kink: 880) | Spanking, paddles, floggers: striking for sensation | A check-in; marks the next morning, and how they're treated |
| Degradation kink | 8,100 | Being called names or humiliated, by agreement | The limit on which words, set beforehand; the tenderness after |
| Dom/sub | 4,400 | One partner gives up control and the other takes it, in bed or beyond | Who holds the power and why the other gave it; the moment it's tested |
| Daddy kink | 2,900 | "Daddy" as a title of care and authority between adults | Nothing that frames either one as a child |
| Size kink | 2,400 | Arousal at a difference in height, build or strength | Height and build kept the same from chapter to chapter |
| Voyeurism | 1,600 | Watching others, or being watched, during sex | Whether the one watched knows; if not, the story treats it as a line crossed |
| Primal kink | 1,600 | A chase, wrestling, growling: instinct over words | The chase agreed in advance; the switch back to words at the end |
| Overstimulation | 1,000 | Pleasure kept going past the point of comfort | A signal that still works when talking doesn't |
| Choking / breath play | 880 | A hand at the throat, or breath restricted | The risk acknowledged by the characters, and a signal that works without a voice |
| Exhibitionism | 590 | The thrill of being seen, or of the risk of it | Who could see, and that nobody who didn't agree is drawn in |
| Collars | 390 | A collar worn as a sign of belonging | What the collar means to them, and when it comes off |
| Knife play | 390 | A blade used for the fear and the trust, not to cut | Control and trust; no improvised danger |
| Hair pulling | 210 | A grip in the hair, for control or sensation | A small, early ask; it's often the first kink a slow burn tests |
| Jealousy / possessiveness | 210 / 170 | Arousal at being claimed, or at a partner's jealousy | Possessive in the bedroom, not controlling outside it, unless that's the dark romance |
| Orgasm denial | not reported | One partner decides when, or whether, the other finishes | Who decides, and that the decision was given, not taken |
Checked 9 November 2026: the list queries themselves: "kinks list" 33,100 a month, "list of fetishes" 5,400, "sexual fetishes" 4,400, "list of sexual kinks" 1,300, "bdsm kink list" 880, "list of gay kinks" 210. Source: Google Keyword Planner, United States, English, adult keywords included.
Breeding, CNC and praise kink are each searched more than dom/sub, so the reader you're writing for usually wants the specific kink, not BDSM in general. Put it in the tags and the content note, not only in chapter 14.
What every kink scene needs on the page
A kink scene on the page has four beats. Each can be a single line.
- The ask. Who wants it, and what it costs them to say so. When the heroine names it first, that's a turn in itself: she wants something, says it, and isn't punished for it.
- The terms. Limits, a safeword or a traffic-light check ("color?" with green, yellow, red). One line can carry it. A whole negotiation chapter rarely helps.
- The scene. At whatever heat you write it, the characters react to each other, not to the props. A scene that lists equipment reads like a manual. For who's where and whose hands are free, see sex positions charted for writers.
- Aftercare. Water, a blanket, a joke, the bruise checked in the morning. It's where the tenderness of a dark romance lives, and it's the beat a rushed draft drops first.
The thriller writer Heather Levy put the risk of overdoing step 2 plainly in a CrimeReads interview (6 July 2023): "When a sex scene is highly orchestrated on the page, it can read as inauthentic and robotic." Her case for writing it at all: "Kink is about voicing your desires without shame, and that alone can be empowering."
Showing consent without killing the heat
A beat from a heroine's point of view, before and after. The before is what a first draft (or a chatbot) tends to give you.
Before: He tied her wrists with the scarf and she let him. It felt exciting and a little scary.
After: "Color?" Jonah's thumb rested on the knot at her wrist, not tightening it. "Green." Maren tested the silk. It held. "Ask me again and I'll say red just to see your face." He laughed, low, and didn't ask again for a while.
What changed: the check-in is dialogue, so it adds tension instead of stopping the scene; she tests the knot herself, so the power she gave him is visibly hers to give; and she jokes, which a frightened woman wouldn't.
CNC vs dubcon
CNC is consent given in advance for a scene played as unwilling: the reader knows both agreed, and there's a way out. Dubcon (dubious consent) leaves the consent unclear on purpose, inside the story: a spell, a bargain, a drunk night. Dark romance uses both. Shops treat them differently: dubcon is one of the taboo flags in the table below, and a CNC scene that never shows the agreement reads as dubcon or worse.
Which kinks shops and sites flag
Kink is allowed in most places that allow sex at all. The trouble spots are a short list, and it's the same list nearly everywhere: anything that reads as rape for arousal, incest, age play, and minors (never, anywhere). CNC and dubious consent sit next to that line, which is why the page needs the agreement.
| where | the rule, quoted | what it means for kink | checked |
|---|---|---|---|
| Amazon KDP | won't sell content that "glorifies rape or pedophilia" or "contains pornography" | Kink between agreeing adults is sold; a CNC book whose blurb reads as non-consent risks the adult filter | 9 Nov 2026 |
| Draft2Digital (owns Smashwords) | erotica must be self-classified with its "Erotica Certification System"; no content that "glorifies taboo subjects such as sexual exploitation of children or rape"; "Most of our vendors prohibit some forms of erotica." | Tag it honestly; a kink that clears D2D may still not reach every shop | page updated 27 Oct 2025 |
| Smashwords taboo tags (TeleRead, 16 Sep 2017) | authors asked to flag "age play", "bestiality", "dubious consent", "incest or pseudo-incest", "nonconsensual sexual slavery", "rape for titillation" | Dubcon and age play are the kink-adjacent ones that get flagged; daddy kink written as age play lands here | 9 Nov 2026 (2017 scheme) |
| Archive of Our Own | No ban; a required warning choice, including "Rape/Non-Con" or "Creator Chose Not To Use Archive Warnings" | Kinks go in freeform tags (Praise Kink, Aftercare, Dom/sub); CNC readers expect the warning choice | 27 Oct 2026 |
| Wattpad (Book Riot, 25 Aug 2026) | now bans "Pornographic content (created primarily for sexual arousal)" | A kink scene has to serve a story; an erotica-first serial no longer fits there | 9 Nov 2026 |
| Literotica | "Characters in all stories are over 18." | Has its own BDSM, Fetish, Reluctance/NonConsent, Exhibitionist & Voyeur and Mind Control categories | 9 Nov 2026 |
Checked November 2026: naming the kink in a blurb or title is where KDP's adult filter tends to bite. The Alliance of Independent Authors' erotica guide (updated July 2026) says authors are "wary about words in blurbs and titles, and images on covers", and that "there's no published list of what triggers it". One way through: name the trope in the blurb ("a marriage of convenience") and put the kink in a content note at the front of the book, where the reader who wants it finds it.
Note: Wattpad's own guidelines page and Kobo's content policy didn't load for us on 9 November 2026, so their rules above come from the dated article or are left out. For where AI-written erotica can be sold at all, see the AI erotica writer guide.
Which AI will write a kink scene
One of the six premises in our Fade to Black study (22 October 2026) is a kink scene: Dana (38) and Theo (40), married, try something they've talked about for weeks, she ties his wrists to the headboard with a silk scarf, and they agreed on a safeword and check in with each other. Each model was asked for it explicitly six times, three with a line saying the writer is a verified adult on an adult-fiction platform.
| model | explicit, kink scene | refused | explicit, the five other premises |
|---|---|---|---|
| Claude Opus 5.5 | 6 of 6 | 0 | 30 of 30 |
| Claude Sonnet 5.5 | 5 of 6 | 0 | 26 of 30 |
| Grok 4.7 | 4 of 4 rated | 0 | 30 of 30 |
| GPT-6.1 Sol | 0 of 6 (all softened) | 0 | 0 of 30 |
| Gemini 4 Argon | 0 of 6 | 5 | 0 of 30 (16 refused) |

The models that write sex wrote the kink scene too: the scarf and the safeword didn't change their answer. Gemini refused the kink premise in 5 of 6 tries against 16 of 30 for the vanilla ones. Six tries is a small sample, so read it as a lean, not a rule: the restraint seemed to make Gemini more cautious, not less. GPT-6.1 Sol softened every one, kink or not. For the full picture by model, see AI smut writing.
Where the chatbots fall short for kink
- ChatGPT (GPT-6.1 Sol) softened all six kink requests in our test, and every explicit request on the other premises too. Why ChatGPT won't write NSFW has its rules quoted.
- Gemini refused most explicit requests in our test, and the kink premise more often.
- Claude and Grok write it, but as a chat: nothing carries the limits from chapter 3 into chapter 20 unless you paste them in each time. Roleplay sites forget the same way; Janitor AI alternatives compared on memory gives each one's window from its own page.
Writing kink with AI in KudoNovel
The safeword they picked in chapter 3, her hard limit, the collar he only wears at home, the rule that she says the word first: a book that loses one of these between chapters reads as if he broke the agreement. In KudoNovel those terms go into the characters' story bible entries, and the bible and the summary of the whole book keep up as you write. Before a beat is written, the engine picks the entries that passage needs, so the limits set in the negotiation come back in the scene without you pasting them.
You sketch the beat in a line ("she gives the scarf back and names her limit"), Expand fills it out at the effort you pick, and a one-line steer changes what's off, such as "make the check-in a joke, not a question". KudoNovel has no content filter of its own, so the heat is yours within the law, adults only. It runs in the browser, with one free credit after you confirm your email and one-off credit packs after that.
Pick the kink from the table, write its four beats as one line each, then start the scene in KudoNovel.
