Short answers, pulled from the story.
The first recorded use of the acronym BDSM appeared on a Usenet newsgroup on the 20th of June 1991. This digital timestamp marked a pivotal moment in the history of human sexuality by creating a linguistic framework for the community.
The term BDSM describes a specific set of erotic practices involving bondage, discipline, dominance, submission, sadism, and masochism. This combination of initialisms formed a new identity that allowed practitioners to distinguish their consensual lifestyle from non-consensual acts of abuse.
Since the 1980s, the community has adopted the motto safe, sane and consensual as the ethical cornerstone for all interactions. This framework distinguishes BDSM from crimes such as sexual assault and domestic violence by requiring informed consent from all participants.
The World Health Organization removed sadomasochism from the International Classification of Diseases in 2018. This decision marked a significant victory for the community and aligned medical classifications with the community's self-identification.
The community ensures safety through the use of safewords and protocols such as the traffic light system where red means stop immediately and yellow means slow down. These mechanisms allow consent to be withdrawn at any moment and require the practice of aftercare to help participants process intense experiences.
