{"product_id":"book-ks0r","title":"Naturally Selective","description":"Researchers of human behavior have identified an \"orgasm gap\": Men usually orgasm during intercourse, whereas women often do not. This book addresses this mystery. The two leading explanations are either that women are \"psychologically broken\"—Freud's theory—or badly designed—the \"by-product theory.\" However, there is a much more compelling third explanation. Evolutionary biology, anatomy, physiology, and direct sex research suggest women have evolved under their own selection pressures and orgasm is a fitness-increasing consequence of such selective factors. This is revealed in their patterns of orgasmic response, which are neither random nor inexplicable.\u003cbr\u003e\u003cbr\u003eKey Features\u003cbr\u003e\u003cbr\u003e● Synthesizes decades of peer-reviewed sex research in anatomy, biology, physiology, and behavior\u003cbr\u003e\u003cbr\u003e● Engagingly written based on feedback from students, peers, and interested lay persons\u003cbr\u003e\u003cbr\u003e● Makes sense of the \"orgasm gap\" between men and women\u003cbr\u003e\u003cbr\u003e● Provides a wider context of human sexual dimorphism and mutual sexual selection\u003cbr\u003e\u003cbr\u003e● Balances sex research and real-world research and practical applications","brand":"Tantor","offers":[{"title":"Audiobook","offer_id":49719537500464,"sku":"BDks0r","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Audio CD","offer_id":49719537434928,"sku":"ZEks0r","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Audio MP3-CD","offer_id":49719537467696,"sku":"ZMks0r","price":45.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0879\/2784\/9264\/files\/ks0r-Square-cover.jpg?v=1780598751","url":"https:\/\/downpour.com\/products\/book-ks0r","provider":"Downpour","version":"1.0","type":"link"}
