unusual to grant consent only for an hour or for an evening. When a scene lasts for more than a few hours, it is common to draft a "scene contract" that defines what will happen and who is responsible for what. It is a good way to work out what all the parties want and usually improves the experience. Some contracts can become quite detailed and run for many pages, especially if a scene is to last a weekend or more. For long term consent, a "slave contract" may be drawn up. Slave contracts are simply a way for consenting adults to define the nature of their relationship and clarify personal boundaries, and are not intended to carry legal force. After a slave contract is drafted, some celebrate the event with a "collaring ceremony", in which the local D/s community is invited to witness the commitment made in the document. Some ceremonies become quite elaborate, and can be as involved as a wedding or any similar ritual. Equipment and accessories Some people maintain a special room or area, called a dungeon or playroom, that contains special equipment, such as shackles, handcuffs, whips, queening stools, and spanking benches or a Berkley horse, for example, used for play scenes, or they may visit a BDSM club that maintains such facilities. Collars Many submissives in a submissive relationship wear a collar to indicate their submissive status and commitment. It can be much like a wedding band, except that only the submissive partner wears one. The traditional collar is a neck band in leather or metal, chosen, designed, and even crafted by the dominant partner. Some subs may wear a "symbolic collar", often a bracelet or ankle chain, which is more subdued than the traditional collar and can pass in non-BDSM situations. It is not uncommon for a sub to have several collars for special occasions. Collars are integral for animal roleplay. Many people—for example, some in the punk rock and goth subcultures—wear collars for other reasons, such as fashion. So, one cannot assume that all people wearing collars are involved in BDSM. Members of the furry fandom may also wear collars as a part of costuming or as fashion. Use of collars in the sexual aspects of furry lifestyle may or may not be connected to BDSM, depending on the individual's preferences. Art and culture Literature One of the most famous works in
