These include wearing the owner's collar, being registered in a slave register, adopting (sometimes legally changing to) a name chosen by the owner, or engaging in a public declaration or ritualized ceremony of some type.Some people draw up a slave contract that defines the relationship in explicit detail.Outside the BDSM community, the relationship of Master/slave is sometimes regarded as a form of consensual sexual slavery. The Master/slave relationship refers to the relationship between the individuals involved, and does not necessarily require any specific acts, sexual or otherwise, though sexual activity is usually an aspect of the relationship.The sexual aspect could be conventional, and not necessarily BDSM.While male "masters" will usually be referred to as "Master," whether or not female Masters are referred to as "Master" or "Mistress" may depend upon whether they identify as following the "Leather" or BDSM path.The Master/slave (or owner/property) relationship is entered into on a consensual basis, without the legal force of historical or modern non-consensual slavery, that is forbidden by the laws of most countries.The participants may be of any gender or sexual orientation.The relationship uses the term "slave" because of the association of the term with ownership rights of a master to their slave's body, as property or chattel.
In BDSM, Master/slave or M/s is a relationship in which one individual serves another in an authority-exchange structured relationship.
Unlike Dominant/submissive structures found in BDSM in which love is often the core value, service and obedience are often the core values in Master/slave structures.
These contracts may also deal with domestic arrangements (such as cleanliness, home duties) and interpersonal relationship matters (such as issues of deference, language, etc.), besides the sexual arrangements.
Typically, they would provide that the Master has the exclusive authority in all matters relating to the body and behavior of the slave, including underwear and other clothing, social relations outside of the arrangement, etc.
A slave could also be a masochist or bottom, but this is not always the case.
