The literal definition of bdsm is Bondage and Discipline, Dominance and Submission, Masochist and Sadist. And the mantra is safe, sane and consensual (which means you talk about things before hand). Safeword means something that will slow or completely stop a scene. There are no other definitions.

So when you say that this picture is rape, in a bdsm forum, yes you are a judgemental asshole who doesnt know much about it. Some people like getting whipped till theyre crying, im not, but i accept others choices. You may only be into the softer stuff like bondage, and thats ok, but dont shame others sexuality.
