" Your ability to withstand pain is your claim to fame. It is ascetic, holy. It is self-control. It is masochism, and masochism pleasurable to many, but we don’t like to think about that. We don’t like to think that a person could have a twisted autoerotic life going on, be both a top and a bottom, and experience both at once: the pleasure of beating the hell out of a body shackled at the wrists, and the pleasure of being the body and knowing we deserve each blow. "
