For some people BDSM is a hobby. For me, BDSM is a legitimate sexual identity, like being gay. It isn't about the spanking and the whipping and the chains. I would be a kinky person without any of that. I'd still want to be in charge. It's who I am.
BDSM forces me to question my role as a disabled woman, to question the expectations I have for myself and the expectations society has for me. Vulnerability is not a weakness. I understand that now. I feel empowered through vulnerability.
