Hi, I'm new to BDSM and I've been trying to think of ways to punish my sub...she is a masochist, so corporal punishment is something she looks forward to, and therefore unaffective. I've already thought of making her stand in the corner, because she is easily bored and it would be real torture, but I'd like some more creative ideas. Exhaustive search of the web has given me things like making her kneel on rice, CR (which is really difficult for her), sleeping on the floor (which I can't do because she has nerve damage from chemotherapy many years ago, and the results would be medically horrific for her), and corporal punishment...which as stated before, she likes too much suggestions, anyone?
