探索BDSM亚文化的核心术语
我们在谈论 BDSM（绑缚与调教、支配与臣服、施虐与受虐）时，常常会遇到一些核心术语和角色类型。对于刚踏入 字母圈（特指BDSM亚文化群体）的新人们，了解这些术语及其背后的含义至关重要。本文将重点解析“Sub”这一核心角色，为你解锁BDSM世界的秘密。
一、什么是Sub？解读书面定义
In BDSM community, "Sub" normally refers to a submissive person. Sub stands for Submissive, which is a role widely adopted in the practice of power exchange in BDSM.
In BDSM culture, "Sub" is an acronym for Submissive, representing a participant who often takes the role of yielding control in BDSM practices. This term is commonly used in dominance and submission (D/s) relationships where one person (Sub) consents to be dominated by another (Dom).
In BDSM context, a Submissive (Sub) is a participant who chooses to yield authority by way of consent. The emphasis is on "consent". Submissive person typically enjoys being controlled or 'dominated' by a Dom during play.
However, female submissives are called "sub" or "submissive"; while "beta" is the term used for a male submissive. This distinction is also cultural, as are the terms tops and bottoms in the context of S/M.（来自Quora）
In the D/s relationship of BDSM, a Submissive (Sub) is "someone you can tell 'no' to in a consensual fashion". In D/s, power flow is from Dom to Sub.
In BDSM contexts, a Submissive is a partner who yields his/hers will in the exchange of power for pleasure with a Dominant partner. This is the "top/bottom" relationship, often found in the circle of S/M.（来自Dom/sub relationships）
More broadly speaking, "Sub" refers to a submissive person. As a role often used in BDSM, it can be found in other contexts as well.
基于以上多种定义，我们可以将 Sub 定义为：在 BDSM 活动中，主动让渡部分控制权、接受支配的一方，其核心要求是自愿、安全、信任。
