Welcome to the BDSM practice education platform of Xilong Home! As a newcomer to the letter circle, you may be curious about this fascinating interpersonal interaction Domain, or you may be unfamiliar with the roles and terminologies in the letter circle.
一、字母圈基础:核心原则与身份认知
The letter circle is the beauty name of BDSM culture, consisting of three core modes: Bondage and Discipline (B+D), Dominance and Submission (D/S), and Sadism and Masochism (S/M). Newcomers should understand their own personality and preferences and try to adapt to roles in practice. The identity is not fixed, but formed through exploration and practice.

BDSM emphasizes role-playing through specific situations and power allocation to explore the multifaceted nature of human behavior. However, in all activities, participants must be aware of and adhere to the principles of "safety, rationality, informed consent." This means:
- Safety: Ensure no risk of physical harm and reasonably assess activity intensity.
- Rationality: Behaviors must be based on clear and sober judgment.
- Informed consent: Before practice, clearly define activity content and boundaries, and reach mutual consensus.
