The source of sexual power is curiosity, passion. You are watching its little flame die of asphyxiation. Sex does not thrive on monotony. Without feeling, inventions, moods, no surprises in bed. Sex must be mixed with tears, laughter, words, promises, scenes, jealousy, envy, all the spices of fear, foreign travel, new faces, novels, stories, dreams, fantasies, music, dancing, opium, wine.
Anaïs Nin, ‘Delta of Venus’.
