Master and slave dating
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.
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.
Such a collar may be a piece of neckwear, or may be a bracelet or other piece of jewelery that symbolizes slave status.
Such a collar is generally not removed except for practical reasons such as medical or security requirements, unless or until the relationship is dissolved; however, a slave is sometimes permitted to wear a more subdued (or less obtrusive) one outside of the home — for example during work or in social situations with people who may otherwise feel uncomfortable.
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.
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.
Slave training is a BDSM activity usually involving a consensual power exchange between two people taking on the roles of a Master or Mistress and a slave.
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.

In BDSM, Master/slave or M/s is a relationship in which one individual serves another in an authority-exchange structured relationship.
The sexual aspect could be conventional, and not necessarily BDSM.
A slave could also be a masochist or bottom, but this is not always the case.
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.
