" When I go to bed with a man,’ he had said once, and Duncan now said for the benefit of the carriage and the complaining woman, ‘I expect him to maintain full erection – full erection – from the moment of nudity onwards. Do I make myself plain? The very first moment of nudity. Anything else – anything that falls short of that – I regard as a personal insult. "
