BDSM actions often take place during a specific period of time agreed to by both parties, referred to as "play," "a scene" or "a session." All parties involved usually derive pleasure from this, even though many of the practices that are performed, such as inflicting pain, humiliation or being restrained would be considered unpleasant under normal circumstances. Sexual intercourse, be it oral, anal or vaginal, may occur within a session, but is not essential.
The fundamental principles for the exercise of BDSM require that it should be performed by mature and responsible partners, of their own volition, and in a safe way. Since the 1980s, these basic principles have been condensed into the motto "Safe, sane and consensual", abbreviated as SSC, which means that everything is based on safe, sane and consenting behavior of all involved parties. This mutual consent makes a clear legal and ethical distinction between BDSM and crimes such as sexual assault or domestic violence.
Some BDSM practitioners prefer a code of behavior that differs from "SSC" and described as "Risk Aware Consensual Kink" (RACK), indicating a preference of a style in which the individual responsibility of the involved parties is emphasized more strongly, with each participant being responsible for his or her own well-being. RACK focuses primarily upon awareness and informed consent, rather than accepted safe practices. Consent is the most important criterion here. The consent and compliance for a sadomasochistic situation can be granted only by people who are able to judge the potential results. For their consent, they must have all relevant information at hand and the necessary mental capacity to judge. The resulting consent and understanding is often summarized in a "contract", an agreement of what can and cannot take place.
In general, it must be possible for the consenting partner to withdraw his or her consent at any given time; for example, by using a safeword that was agreed on in advance. Failure to honor a safeword is considered the most serious misconduct that can take place in BDSM and can even change the sexual consent situation into a crime, depending on the relevant law, since the bottom has explicitly revoked his or her consent to any actions which follow the use of the safeword.
Bondage and Discipline
The term "Discipline" describes the use of rules and punishment to control overt behavior in BDSM. Punishment can be pain caused physically (such as caning), humiliation caused psychologically (such as a public flagellation) or loss of freedom caused physically (eg. chaining the Bottom to the foot of a bed). Another aspect is the structured training of the Bottom. Overlap with practices from the field of bondage can occur, but is not necessarily mandatory. A differentiation between bondage and discipline is sometimes difficult.
Dominance and submission
"Dominance and submission" (also known as D&s, Ds or D/s) is a set of behaviors, customs and rituals relating to the giving and accepting of dominance of one individual over another in an erotic or lifestyle context. It explores the more mental aspect of BDSM. This is also the case in many relationships not considering themselves as sadomasochistic; it is considered to be a part of BDSM if it is practiced cognizantly. The range of its individual characteristics is thereby wide.
Examples of mentally orientated practices are education games, during which the dominant requires certain forms of behavior from the submissive. Special forms include erotic roleplay like ageplay, in which a difference in age, either real or enacted, formulates the background; or petplay. Concerted deployed sexual rejection exercised on the partner can be an aspect of Dominance and Submission as well (see cuckoldry). The most established and probably most cliché set form of dominance and submission is dominance and slavedom. These can be administrated for the short duration of a session among otherwise-emancipated partners, but also can be integrated into everyday life indefinitely. In a few relationships, it leads as far as total submission of one partner in the truest sense of the phrase total power exchange. Compensating elements of the total dominance and submission are care and devotion complementing one another, thus facilitating stable relationships. The consensual submission of the sub is sometimes demonstrated to others by symbols indicating his/her belonging to the dom, such as wearing a collar, special tattoos, piercings, a very short haircut or a bald head.
Occasionally, actual "slave contracts" are set out in writing to record the formal consent of the parties to the power exchange, stating their common vision of the relationship dynamic. Such documents have not been recognised as being legally binding. Contracts that are contra bonos mores (contrary to public morals) are generally illegal, and such contracts can even be constitutionally prohibited. In Europe, such agreements may be contrary to Article 3 of the European Convention on Human Rights which grants a general freedom from "unhuman or degrading treatment". This right had been held to be absolute and no limitations or derogations are permitted by the Convention. Nevertheless, the mere existence of such purported contracts has resulted in banner headlines in yellow press publications, and uninformed third parties seeing such information out of context are periodically led to rejecting and condemning the relationships they describe.

Tie and Tease
Tie and tease refers to the BDSM practice of tying up a partner for sexual pleasure and then denying him or her an orgasm.
Often, the bound person will be gagged so as to increase their sense of helplessness. They may also be blindfolded for the same reason, or not blindfolded so that they can see their teaser being provocative by for example dressing in lingerie or having sex with a third person. There may be an intimate examination.
