Physical bondage can join limbs, hold them apart, attach the body to a fixed point, limit its range, or wrap much of it. Homosaurus describes restraints as tools and devices such as cuffs, ropes, chains, straps, and straitjackets. A partner's grip can also restrict movement even though no equipment stays on the body.

Some bondage is functional. Its job is to keep a limb or the whole body in place. Some is decorative, with lines, materials, or poses chosen mainly for their appearance. Many scenes combine the two. A harness can change posture and make a visual pattern, while a soft restraint can create a strong sense of being held even when movement remains possible.

Self-bondage means restraining yourself. In partner bondage, one person applies or directs the restraint and another receives it. The National Coalition for Sexual Freedom glossary calls these activity roles top and bottom. They do not automatically make the people dominant and submissive outside the activity.

Some kink communities also use honour bondage for an instruction to stay still or hold a position without physical restraint. The Lascivity kink glossary records this community usage. It is a symbolic extension of bondage, since obedience rather than equipment creates the restriction.

• Joining wrists, ankles, or other body parts
• Holding limbs apart or within a set range
• Attaching the body to furniture or another fixed point
• Wrapping or enclosing part or most of the body
• Using restraint mainly for shape, pressure, display, or stillness

A bondage-specific study of 514 messages posted to an international discussion group in 1990 found that the most frequent reported experience was playful exploration of new sexual pleasure. Other recurring experiences were power exchange, intensified pleasure, tactile stimulation, and bodily sensations. The unit was messages in one group, so the findings describe what that group wrote about, not how common each motive is among everyone who likes bondage.

Physical containment can make touch and anticipation more noticeable because a person cannot reach, turn, or adjust in the usual way. Pressure from a restraint may be part of the pleasure. For someone else, the draw is visual: the outline of a pose, the contrast between body and material, or the process by which a restraint takes shape.

Emotional meanings vary too. The person applying the restraint may enjoy control, planning, craft, display, or watching a response. The person receiving it may enjoy surrender, stillness, exposure, being held, or relief from having to act. A switch may like both sides for different reasons.

Restraint makes control visible, which is why bondage often appears in dominance and submission. The NCSF glossary distinguishes activity roles from relationship roles: a top does or directs an activity and a bottom receives it, while dominance and submission describe authority. The same person can be a bondage top without being a dominant, or a bondage bottom without being a submissive.

The person who is physically bound may still direct the pace, position, and purpose of the activity. A rope bottom can help a rigger practise a pattern. A model can choose the pose while a photographer or binder follows the plan. The physical position alone does not tell you who has authority.

Capture and interrogation are fantasy or roleplay frames. The real arrangement is an activity people chose, even when the story is about having no choice. The fantasy label does not describe an interest in restraining an unknowing person.

Bondage is the broad category. The Homosaurus vocabulary places rope bondage and erotic mummification beneath bondage. Rope bondage is one method with its own materials, techniques, roles, and visual traditions. Mummification and encasement restrict much more of the body. Predicament bondage makes a choice between positions or sensations part of the experience. Sensory deprivation may accompany any of them, but blocking sight or sound is a separate interest from restricting movement.

The word bondage existed long before its sexual use. Oxford's entry gives its Middle English origin and lists an older formal meaning of enslavement or imprisonment alongside the erotic meaning. Erotic bondage and sexual bondage remove that ambiguity when the context is unclear. B and D means bondage and discipline, and Merriam-Webster dates its first known use to 1971. The NCSF glossary treats bondage and discipline as different ideas: bondage secures a person, while discipline uses control to enforce rules.

Modern fetish publishing in English is one documented part of this history. Julia Pine's peer-reviewed study of John Willie's Bizarre describes a fetish magazine produced in Canada and the United States in the 1940s and 1950s. It used familiar popular press forms to work around censorship and helped codify a US fetish subculture. The magazine carried bondage imagery alongside fashion and other fetishes. This helps explain the visual vocabulary around bondage, but it is not an origin story for erotic restraint as a whole.

Start with what attracts you. You might like reduced movement, snug pressure, the sight of restraints, the craft of applying them, or the power relationship created by a locked cuff. Those are different interests even when they produce the same photograph.

It also helps to separate fantasy from wanted experience and to name intensity. Decorative wrist ties, strict immobilisation, spread positions, furniture, suspension, and encasement ask very different things of the body and the people involved. Naming the versions that appeal is clearer than relying on one role or intensity label.

Useful preference language is specific: 'I like my wrists held but want my legs free,' 'I am interested in rope as an art form,' or 'The idea of being secured to furniture is more appealing than wearing cuffs.' No single bondage identity has to cover every version.
