Bondage

What is bondage?

Bondage is consensually tying up, cuffing or otherwise restraining a partner, for the arousal, the look of it, or the physical feeling it gives. It is the B in BDSM. What gets used ranges from rope and cuffs to a scarf or a necktie.

What bondage looks like in practice

For most people bondage starts with something that is already in the house. A scarf around the wrists, hands above the head, a necktie to a bedpost.

What happens then is not physical but mental. The encyclopedia describes the appeal as the freedom that comes with physical passivity, and as the psychological arrangement in which control is handed over. You cannot do anything anymore, and so you do not have to.

The heavier end looks different. A box tie that pins the arms behind the back, a hogtie, a chest harness, or a full suspension in rope. Between those lies an enormous range, and almost no one works through all of it.

How it works, and where the limits lie

The risks of bondage are better documented than those of almost any other form of BDSM, and they are not vague.

There are two kinds of problem. The first is circulation. When the outflow is blocked the skin turns red and then purple, and when the inflow is blocked it turns white. The best-known rule of thumb belongs here: the rope has to be loose enough to slide two fingers under it.

The second is more serious. The account of bondage techniques is blunt about it. Nerve damage happens very fast, is cumulative and often irreversible. The vulnerable spots are the knees, elbows, groin and armpits, and the radial nerve in the upper arm.

That is not theory. Khodulev and colleagues show in Cureus that a short suspension can already be enough to knock out extension of the wrist and fingers, and that recovery can take months. In their group the radial nerve was the affected nerve in nine out of ten rope injuries.

Why people do it

The appeal is in the loss of choice. Someone who is tied up no longer has anything to decide, and for many people that is the whole point.

What measurably happens has been studied once. Sagarin and colleagues took saliva samples from 58 people practicing BDSM in Archives of Sexual Behavior and saw cortisol rise in those who were tied up, received stimulation and followed orders. In the ones who said afterward that it had gone well, that value dropped again and the felt connection went up.

• For the person tied up, the gain is rest: no decisions, no performance. And the mind gets no room to be somewhere else.
• For the person tying, the gain lies in attention and care. Hébert and Weaver found in The Canadian Journal of Human Sexuality that dominants describe themselves as empathetic, caring, attentive and responsible, and that they name “more work and responsibility” as the flip side.
• For a couple, the payoff is that the conversation gets concrete: how tight, how long, and what to do if something does not feel right.

Nerve damage does not ask whether someone enjoyed it. Bondage is the form where good intentions help the least.

How people do it

The usual route runs from soft to tight and from short to long. Wrists first, then arms, then more, checking along the way whether the hands stay warm.

What separates the careful from the sloppy is presence. The encyclopedia states two things outright. Never leave someone who is tied up alone, and keep a pair of scissors within reach so you can cut them loose in an emergency. On top of that, change position at least once an hour.

For some positions, being short is built in. Strappado and suspension, according to that same source, do not allow long periods, because of the risk of lasting damage to joints and tissue.

Which forms exist

The ordering most people use runs along the body, not along the level of difficulty.

Upper-body ties are the best known. The box tie sets the arms behind the back with the forearms horizontal; chest bondage lays bands above and below the breasts. Both sit close to the radial nerve, which makes them the place where most damage happens.

Lower-body ties run from an ankle tie to a frog tie, where the lower leg is set against the thigh. The hollow of the knee and the groin are the spots to avoid here.

Whole-body ties are the hogtie and the shrimp tie, where the body is forced into a single shape. These are positions you cannot hold yourself, and so positions where the clock is the most important tool.

Suspension stands apart from that. Partly or fully off the ground, with the weight on a few points instead of spread across the body. That is the category the documented nerve injuries come from.

Alongside that there is the whole world of gear that replaces the rope: cuffs, an armbinder, a straitjacket, bondage tape or a trestle. Each of those shifts the risk. Metal pinches more sharply than rope, tape cannot be readjusted, and a piece of furniture takes over the work of holding a position but makes time itself less noticeable.

What all these forms share is that the intensity is not in the technique. For most people, two wrists in a scarf do exactly the same thing as an elaborate tie; what differs is how it looks and how much can go wrong.

Misconceptions about bondage

“If it does not hurt, it is fine.” Nerve compression does not hurt at first. The first signal is tingling or numbness, and that is already late.

“Tighter is better.” The two-finger rule exists because being tied tight adds nothing to the feeling of being tied. What it does add is risk.

“Suspension is the logical next step.” Suspension is a different category, with its own risks and its own learning curve. Anyone who does not yet have a sure hand on the ground does not belong in the air.

“Cable ties and tape are handy.” They are cheap and they hold fast, and that is exactly the problem. You cannot readjust them and they cut in the moment someone pulls. Anything you cannot loosen in one motion does not belong around a wrist.

What I see myself

I have been doing bondage for twenty-five years now, with real hemp rope, and on a BDSM date it is the part I have grown slowest at.

Surprisingly little is needed. People come in with images of complicated patterns, and what actually happens is that two wrists are tied and someone, for the first time in months, has to do nothing. The pattern is for the photo; the being tied is for the head.

Along the way I ask whether the hands are warm. Not whether it feels good. To that first question I get a usable answer, to the second one usually not.

And one thing I hear from women that is written down nowhere: the moment something happens is not when the rope goes tight, but when the first length of rope passes over the skin. Everything after that is confirmation of what has already been decided by then.

What you can do yourself

• Keep two fingers of room between rope and skin. That is not a beginner’s guideline but the basic rule.
• Have scissors ready that let you cut loose in one motion, and test that they get through your rope.
• Stay present. Someone who is tied up is never left alone in the room, not even for a moment.
• Change position at least once an hour, and ask about tingling instead of about pain.
• Stay away from knees, elbows, groin and armpits. That is where the nerves that damage the fastest lie.
