Dia Zerva finds pain as cathartic because she does sensual. It enables her to concentrate all her ideas on one stage and enable the world to simply fade away. The tightness of the bondage makes her feel secure. The potency of Cyd Black makes her feel safe. It is odd what happens in her head. Everything that he does hurt her , however, she would not exchange it for anything in the world. Bondage and entry make her feel whole. Without them she is nothing.
