Trigger

What is a trigger?

A trigger is something that sets off an intense, unwanted reaction in someone because it resembles something from an earlier experience. It can be a sound, a smell, a sentence, a posture. The word comes from everyday language, not from diagnostics: the DSM-5 speaks of traumatic reminders.

What a trigger looks like in practice

Rarely as the subject where you’d expect it, and almost always more specific.

An example you see often in this work: someone can take anything, from being tied up to a firm hand in her hair, but not something coming over her mouth from behind. Not because it hurts and not because she doesn’t trust him. Her body gets there before her thought, and only afterward does she remember where it comes from.

That’s the pattern: a trigger usually sits on a detail of the act, not on the act itself. The direction someone approaches from, a word said in a certain tone, a perfume, the sound of a belt buckle. Look only at the subject and you’ll miss it, and the same goes for looking only at the intensity.

Where the word trigger comes from

From Dutch, and only much later from psychology.

Etymonline dates trigger as a noun to the 1650s, tricker before it in the 1620s, and gives its origin as the Dutch trekker, from trekken. The verb to trigger, “to cause something”, dates only to 1930. And the meaning this page is about, “cause an intense and usually negative emotional reaction”, is according to that same dictionary recorded only from 1986.

That’s worth knowing, because it refutes the assumption that this is a clinical term the scene borrowed. It’s the other way around: an everyday word that made its way through common speech into conversations about trauma, and that was never taken into the manuals themselves.

What naming your triggers gets you

Mainly that the other person doesn’t have to guess, and you don’t have to hope.

• For you, it means you say something uncomfortable once and can then let it go, instead of guarding the whole evening for whether it comes up.
• For the other person, it’s the difference between watching for everything and watching for one thing. A specific heads-up makes someone a better partner in the conversation, not a more cautious one.
• For the two of you together, it removes the main reason people shut down halfway through without saying why.

Naming dismantles nothing. A trigger you’ve spoken out loud can still land exactly as hard, and sometimes it comes from a direction no one expected. What you gain by naming it is not that it won’t happen. It’s that an agreement is ready for when it does.

Where scene usage and clinical usage part ways

“A trigger is anything you can’t handle well.” In everyday language, yes by now; in the clinic, no. The criteria the National Center for PTSD summarizes call for exposure to life-threatening danger, serious injury or sexual violence, for symptoms lasting longer than a month, and for distress or impairment in daily life. A dislike of a word doesn’t meet that. Both ways of talking are allowed to exist, but they aren’t the same, and that difference vanishes the moment you use the same word for both.

“A warning beforehand makes it softer.” That’s been researched and it isn’t true. Victoria Bridgland, Payton Jones and Benjamin Bellet brought together all empirical studies on trigger and content warnings in Clinical Psychological Science. Their result: “warnings had no effect on affective responses to negative material or on educational outcomes. However, warnings reliably increased anticipatory affect.” So the warning didn’t soften the reaction and it reliably increased the tension beforehand. That research is about warnings on texts, films and images, not about a conversation beforehand with someone who’s going to touch you; a negotiation exists to determine what happens, not to prepare your feelings.

“Avoidance is the solution.” For the evening itself, yes: something you don’t want doesn’t happen, and no discussion goes with that. As a rule to live by it’s different. Avoidance appears in those same criteria as a symptom, not as a solution, and what you do about that is a question for your own therapist. A date is not treatment, and I don’t pretend it is.

“It’s a word from psychiatry.” No. It’s a word from a weapon’s mechanism, borrowed from Dutch, recorded in this meaning only from 1986 and found nowhere in the DSM-5.

What I see myself

I’m Victor, a gigolo, twenty-five years active in BDSM and trained as a psychotherapist. What strikes me most often is that women apologize before they tell me. As if a trigger were a flaw that makes the evening smaller, while it works exactly the other way around: the sharper I know where the edge lies, the further we can stay away from it without the conversation being about it.

The second pattern: people tell me the history when what I need is the signal. I don’t need to know what once happened, and I don’t ask about it either. What I need to know is what must not happen, how I’ll notice if it goes wrong anyway, and what has to happen then.

And the most practical observation: when it goes wrong, talking usually stops first. That’s why, alongside a safeword, I always agree on a stop signal, and I add that going quiet means the same as stop to me.

What you can do yourself

• Say what you need, not what happened to you. “Not from behind” is usable; a story isn’t required, unless you want to tell one.
• Agree on what happens if it happens anyway. Everything stops, or everything stops except the holding. You want that difference settled beforehand.
• Have a sign that works without a voice, because a safeword you can’t get out at that moment is no safeword.
• Put it in the same conversation as your medical information, so beforehand and not halfway through.
• If you’re in treatment for this, coordinate it with your therapist. What’s sensible on an evening and what’s sensible in treatment can diverge, and that judgment belongs there and not here.

Further reading on triggers

Within this glossary, negotiation explains how the conversation beforehand is built, safeword describes what happens when you intervene, and aftercare covers the hour after, in which a reaction sometimes only lands then.

Beyond that, the National Center for PTSD page is the shortest reliable summary of exactly what the diagnosis requires, and the meta-analysis by Bridgland and colleagues is worth reading for anyone who thinks a warning helps on its own.

Where this fits on this site

If you have something you want to work around, that’s not a special request, it’s simply information I want to have beforehand. The page on the BDSM date shows how that conversation goes and what we agree on before anything starts.

The official summary of the DSM-5 criteria by the U.S. knowledge center for PTSD, with the note on the page itself that the full criteria are copyrighted by the American Psychiatric Association. Provides criterion A (exposure to life-threatening danger, actual or threatened serious injury, or actual or threatened sexual violence), criterion B with “Emotional distress after exposure to traumatic reminders” and “Physical reactivity after exposure to traumatic reminders”, criterion C with avoidance of trauma-related stimuli, criterion F (“Symptoms last for more than 1 month”) and criterion G (symptoms cause distress or impairment). It thereby also provides the negative finding this page leans on: the word trigger does not appear in those criteria.
