I highly doubt this is a genuine thread, but, in case anyone else is curious. BDSM is about trust and consent. The playpartners need to communicate openly and set out what they are comfortable with, what is an option (soft limit) and what is a definite no (hard limit). Even during BDSM you can stop at any time, and any continuation after you've explicitly removed your consent is rape or sexual assault.
BDSM is not abuse.
