Some anthropological studies relate only indirectly to sexual matters. In Frazer "The Golden Bough" and Crawley "The Mystic Rose", there is a vast amount of both sexual and non-sexual information. The two most famous anthropological studies that bear directly on sexual matters are Malinowski's "The Sexual Life of Savages" and "Patterns of Sexual Behaviour" by Ford and Beach. If any hardy reader is ploughing through the superlatives in this book he will already have met Ford and Beach several times. Their book, as one of the few cross-cultural studies to include reference to animal behaviour also, is perhaps the most quoted of anthropological studies of human sexual behaviour.
