Lady Chatterley's Lover by D.H. Lawrence

"'It's an amazing idea, Charlie,' said Dukes, 'that sex is just another form of talk, where you act the words instead of saying them. I suppose it's quite true. I suppose we might exchange as many sensations and emotions with women as we do ideas about the weather, and so on. Sex might be a sort of normal, physical conversation between a man and a woman.'"
