Thomas Pynchon said this quote
“ Why will the Structure allow every other kind of sexual behavior but that one? Because submission and dominance are resources it needs for its very survival. They cannot be wasted in private sex. In any kind of sex. It needs our submission so that it can co-opt us into its own power game. There is no joy in it, only power. I tell you, if S and M could be established universally, at the family level, the State would wither away. ”
