"А Sadist without a philosophy is a bully. If you do not understand your Sadism you cannot control it; it will control you. A
masochist without a philosophy is a victim. If you do not understand your masochism you cannot offer it to another; you will
submit only to your own misunderstood needs. Let me ask you then, be you Top or bottom, “Why do you hurt?"

Дэвид Стейн (ок. 1985-87 гг.) "The Book Of Edge"
