Gammas and BDSM

[Faith]

I’m really confused.
I thought consensual non-consent was a thing? And that it wasn’t the same as harming someone or sexually violating them...?

...? Is it? https://arcaneadvice.com/all-lessons-a-z/consensual-non-consent-a-healthy-definition-for-ds

I just saw your question.
I don't know anything about bdsm. In any case, non consensual sex is rape by definition and is violence which means harming someone.

Rape, sexual assault, and sexual abuse can have different legal definitions. In general, rape, sexual assault, and sexual abuse are forms of violence in which there is sexual contact without consent
