欢迎来到西檬之家的新人入门指南。本篇特别聚焦于字母圈（BDSM）中一个特殊术语——"圣水"，同时带领大家了解SSC原则及安全词制度等把持 BDSM实践的核心原则和术语，帮助各位新人安全、愉快地融入这个既有趣又充满张力的世界。
首先，我们先来了解一下什么是 BDSM——这个源自英文 Sadism & Bondage & Discipline & Dominance & Submission &Masochism 的术语，指的是通过绑缚与调教、支配与臣服等多样化性互动模式，建立在信任与同意基础之上的一类亚文化实践。熟悉了这些术语的含义，你将更容易理解二人之间的互动规则和界限。
一、BDSM新人认知地图：从术语解释开始
在正式探讨圣水之前，我们有必要为你简单解析一些 BDSM 中常见的基本术语，如下：Dominant (Dom)，指的是能够掌控他人并弓|导其行为达到目标的人。与之相对，处于被支配地位者通常称为 submissive (Sub)，他们往往乐于服从支配者的指令、情感需求等。除此之外，还有主要追求施虐快感和受虐快感的人分别被称为 Sadist (S) 和 Masochist (M)。深入了解这些角色的本质，能帮助你判断自己的兴趣点在哪一个方面，从而为深入实践打下基础。
二、"圣水"的定义和背景：是什么，为什么玩？
在 BDSM 社群，尤其是 D/S（支配与臣服）互动中，你可能会遇到一个略带神秘感的概念——圣水——这是一篇针对新入圈人士的专项解析。
圣水，按照 BDSM社群的说法，有着非常有限的定义。狭义上，它是指人尿液；广义上，也可能引导至伴侣洗脚水、唾液等多种液体，大多是对上位者（Dom/Daddy）身体的排泄物所带来的刺激与征服感，体现出服从与征服之间的微妙互动关系。
可以说，圣水是一个非常另类的玩法，主要在强调爱护的实践中侮辱臣服者，或将尿液作为奖励和征服情人的诱惑方式等。这种形式完全凭二人之间的共同兴趣、 Nullable: { "title": "", "seo_title": "", "seo_keywords": "", "seo_description": "", "excerpt": "", "content_html": "" } SQL语句错误：未指定目标表 Error: Got error 28 from storage engine The otherysql.statement is: INSERT INTO storage_engine_error_log (log_date, log_message) VALUES ('2024-01-04 22:05:59', 'Error during execution of\'INSERT IGNORE INTO storage_engine_test (id) VALUES (2),(3)\'\nError Message: Duplicate entry \'2\' for table storage_engine_test') To help debug, follow the instructions in the documentation. Error Code: 1062 Duplicate entry '2' for table 'storage_engine_test' SQL Statement Tested: Unfortunately, we keep getting an error when using the above SQL statement. I would like to understand why. Here are the table creation and insert details: table: storage_engine_test columns: ID INT NOT NULL AUTO_INCREMENT PRIMARY KEY, created DATETIME NOT NULL, PRIMARY KEY (id, created) Sample data:\nINSERT INTO storage_engine_test (id) VALUES (2),(3) The error message says there's a duplicate entry for id 2, but in my insert I only have id=2 once. Any idea why this is happening? The only thing I can think of is that there is already some data in the table with id=2, and when I try to insert it again, it causes the duplicate error. But why would inserting just one row cause this issue? I thought AUTO_INCREMENT would prevent the conflict. Wait, the table definition has a composite primary key on (id, created). That means both columns must be unique. So, perhaps there's an existing row with the same id and some different created timestamp? But my insert statement doesn't specify the created column at all. Normally, the created column would be set to the current timestamp automatically if it's a DATETIME column without a default value. In this case, my insert statement is: INSERT INTO storage_engine_test (id) VALUES (2) But my table creation statement is: CREATE TABLE storage_engine_test ( id INT NOT NULL AUTO_INCREMENT, created DATETIME NOT NULL, PRIMARY KEY (id, created) ) ENGINE=InnoDB;
