Edgeplay

What is edgeplay?

Edgeplay (Dutch: edgeplay) is BDSM whose risk cannot be removed, only reduced. The encyclopedia describes edgeplay as risk-aware consensual kink that can be physically or psychologically unsafe. Where the rest of BDSM can be made safe with care, that does not hold here. Where that line lies differs from person to person.

What edgeplay means in practice

Edgeplay is not playing harder. It is playing with a risk that stays no matter how well you do it.

Take ropework in suspension, known in the scene as shibari. Khodulev and colleagues described in Cureus nerve damage from Japanese ropework, where in 90 percent of the cases the radial nerve was affected, the nerve that runs down the upper arm. Recovery ranged from a few minutes to several months.

What that study shows most sharply is not the severity but who it happened to. The four riggers surveyed had three to five years of experience and did about a hundred ties a year. Two of them suffered damage more than once themselves. Experience makes the chance smaller, then, and not zero, and that is exactly what edgeplay means.

The second example is heavier. For play around breathing there is no technique that removes the risk, only an approach that reduces it. That is a subject where care and experience come first above all, precisely because things have gone wrong in the past.

With that kind of incident it is almost always people who were alone, without anyone who could step in. What is known about the partner variant is at breath play.

Where the word edgeplay comes from

From the edge, and from an argument about the word “safe”.

For years the scene had one slogan: safe, sane and consensual. For part of what people did the first word simply did not hold. In 1999 Gary Switch therefore came up with RACK, risk-aware consensual kink, and posted it to the USENET list of The Eulenspiegel Society. The encyclopedia entry on RACK sums up the difference in one sentence: RACK acknowledges that nothing is ever 100 percent safe, so within RACK there is no “safe” or “unsafe” but only “safer” and “less safe”.

That same article makes the link with this term explicit: RACK leaves more room for practices that others would label edgeplay, precisely because risk tolerance differs from person to person. One word names the play, the other the framework within which it can be justified.

What that framework changes in practice is the order of the conversation:

1. Name what can go wrong. Not in general, but concretely: which nerve, which substance, which duration, which injury.
2. Establish whether both people understand that. Dunkley and Brotto state in Sexual Abuse that the feature separating BDSM from abuse is the presence of mutual, informed consent of everyone involved. With edgeplay the word “informed” carries the most weight.
3. Only then agree what happens, including what the end is and who steps in.

Why people do edgeplay

For the conscious presence of real danger, and for what that does to your attention.

The pull is in the awareness that it is serious. Anyone who knows something can go wrong is fully present; there is no room left for the groceries or tomorrow. On top of that, crossing a line you thought you would never get past does something to how you see yourself.

What it gives each person involved:

• For the one who receives, the payoff is that trust is no longer a word but something you lie down on. You need someone else to survive this, and you feel it.
• For the one who takes the lead, the gain is in the concentration it demands. This kind of play forces you to pay attention, and that state of attention has its own name in the scene: domspace.
• For two people together, the conversation beforehand changes. Anyone who has to explain which nerve runs where and what happens if it goes wrong is talking about things that never come up in an ordinary relationship.

None of those payoffs has been measured in research; they come from what people say about it, including what I hear myself. What has been measured is about nerve damage and about how badly it can go wrong. Edgeplay also fixes nothing: anyone who uses it to save a relationship or to punish themselves is doing something other than play. And this belongs firmly with it: there is no version of this play that is safe when you are alone.

How people actually do edgeplay

The usual route is strikingly slow: people first learn one specific form thoroughly, and do not start on the rest.

That is because the knowledge differs per practice. For ropework you need to know where nerves run close under the skin. For play with electricity the rule is that nothing goes above the waistband or across the heart. For blades and needles it is about skin, hygiene and the cleanup afterward. There is no general edgeplay skill, only a stack of separate ones.

How thoroughly people talk about it depends on the risk, and that has been measured. Tarleton, Mackenzie and Sagarin put to 202 BDSM practitioners how acceptable certain ways of negotiating are, in Archives of Sexual Behavior. Their participants found thorough negotiation more important the riskier an activity is. From that same study comes the asymmetry that matters most for this kind of play: taking something away during a scene was found far more acceptable than adding something.

The difference between the careful and the sloppy execution is therefore not in nerve, but in who can still step in. A scene with the phone out of reach looks like a scene with scissors on the table, until the moment it goes wrong.

Misconceptions about edgeplay

“Edgeplay is the same as edging.” No, and that is the most stubborn mistake on this page. Edging is steering an orgasm; edgeplay is a set of practices that has nothing to do with it. The resemblance is only in the word.

“Edgeplay is for the advanced.” Half true. The encyclopedia calls the boundary explicitly relative: what is edgeplay for one person is ordinary for another. A blindfold can weigh more heavily on someone with a history of anxiety than a cane on an experienced masochist.

“If you do it right, it is safe.” That is exactly what the word denies. Within RACK there is only safer and less safe. The nerve study by Khodulev and colleagues shows that even riggers with years of experience and a hundred ties a year suffer damage.

“Edgeplay stands outside the ordinary rules.” The other way around. Dunkley and Brotto show that mutual informed consent is precisely the feature that separates BDSM from abuse, and with edgeplay that feature is the only thing standing between them.

“It is a fixed list of practices.” No. The encyclopedia entry on edgeplay gives examples and no definition per practice, and has carried since March 2014 a notice that the article needs more sources. That is, honestly, the level of documentation this term has to make do with.

What I see of it myself

I am Victor, a gigolo, in the BDSM world since 1990 and with a background as a psychotherapist. Part of what falls under edgeplay I do on a BDSM date: breath and choke play, CNC, needles, candle wax. Lasting physical or emotional damage is on my hard-limits list, and that is not a slogan but the reason some requests do not go ahead.

How people bring it up says the most. Almost never with the practice itself. Usually with a ten-minute detour, and only then the question. That says a lot about shame and little about risk.

The second thing: people systematically underestimate the psychological part. A needle gets thought through. What fear play does the next day, not. I have called off a scene more often because of what was going on in someone’s head than because of what would happen to her body.

And this is the dividing line for me. I always ask why someone wants this exactly. If the answer comes from curiosity, we go ahead. If it comes from punishment or from despair, we talk instead. That is not meant to be polite; it is the only way I can do this work.

What you can do yourself

• Learn one form well instead of five a little. The knowledge differs per practice and there is no general edgeplay skill.
• Name the concrete injury before you agree to anything. Which nerve, which substance, how long. “I know it is risky” is not informed consent.
• Do nothing from this category alone. Being alone is the one pattern that comes back in nearly every incident, and the only one you can rule out beforehand.
• Agree that taking away is always allowed and adding never. That is how experienced BDSM practitioners see it too, and here it is the difference between less safe and irresponsible.
• Lay out what you need to stop: scissors within reach, phone charged, nothing between you and the exit.
• Plan the days after, not just the evening. With fear and edge play the bill comes later; what can flare up then is at drop.
• Ask yourself why you want this. Curiosity is a reason. Punishment and despair are not, and then the conversation belongs before the play.

More reading about edgeplay

On this site the heavier parts are worked out separately: breath play, blood play, cutting, branding and CNC. The blog category on the dangers of BDSM covers the risks in plain language, and the article on safety in the BDSM context describes the agreements underneath them.

Off this site, the review article by Dunkley and Brotto is the best starting point: it explains what sets consent within BDSM apart from abuse and gives criteria for recognizing that difference. For anyone who does ropework, the article by Khodulev and colleagues is free to read and required reading: it names exactly where on the arm it goes wrong.
