Safe, sane, and consensual (SSC) is one of the philosophies surrounding ethically acceptable behavior in BDSM, kink, and alternative sexuality communities. Safe means that the risk of activities should be understood by all participants and either eliminated or reduced as much as possible. Sane refers to the need to approach activities in a sensible and realistic frame of mind, and with an understanding of the difference between fantasy and reality. Consensual means that all participants have freely consented to the activity and were in a state of mind to do so.
