“In an electroencephalogram… one of her seizures was almost identical to an orgasm... Nothing happened during a seizure that couldn’t happen outside one, except that Roselyn was not in control of it and it happened all at once. Since then, she had experienced hundreds of orgasms and dozens of seizures and, though she didn’t come close to finding the latter nearly as entertaining as the former, it was always in her mind. In the midst of Dryden’s often machine gun lovemaking or her own considerably more directed and soft ministrations, it was always in the back of her mind at the moment of climax—this is a tenth of a seizure, this is a fifth of one.”
