The book on sex in the twenty-first century “Alfred Kinsey only scratched the surface. Interviewing a mere 18,000 horny humans? Please . . . Drs. Ogas and Gaddam [offer] hot new scientific findings.”—The Washington Post Want to know what really turns your partner on? A Billion Wicked Thoughts offers the clearest picture ever of the differences between male and female sexuality and the teeming diversity of human desire. What makes men attracted to images and so predictable in their appetites? What makes the set up to a romantic evening so important for a woman? Why are women’s desires so hard to predict? Neuroscientists Ogi Ogas and Sai Gaddam reveal the mechanics of sexual relationships based on their extensive research into the mountains of new data on human behavior available in online entertainment and traffic around the world. Not since Alfred Kinsey in the 1950s has there been such a revolution in our knowledge of what is really going on in the bedroom. What Ogas and Gaddam learned, and now share, will deepen and enrich the way you, and your partner, think and talk about sex. ?When it comes to sexual arousal, men prefer overweight women to underweight women, and a significant number of men seek out erotic images of women in their 40s, 50s, and 60s. ?Women enjoy writing and sharing erotic stories with other women. The fastest growing genre of erotic stories for women are stories about two heterosexual men having sex. ?Though the male sexual brain is much more different from the female sexual brain than is commonly believed, the sexual brain of gay men is virtually identical to that of straight men. Featuring cutting-edge, jaw-dropping science, this wildly entertaining and controversial book helps readers understand their partner's sexual desires with a depth of knowledge unavailable from any other source. Its fascinating and occasionally disturbing findings will rock our modern understanding of sexuality, just as Kinsey's reports did sixty years ago.
