I am Justin Lehmiller, a Research Fellow at The Kinsey Institute who conducted the largest survey of sexual fantasies in America and just wrote a book about it. AMA!
Short bio: I am a Research Fellow at The Kinsey Institute (Indiana University) and author of the blog Sex and Psychology (https://sexandpsychology.com). I have researched and taught about the science of sex for the last 10 years, including 3 years at Harvard, where I taught a popular sexuality course. I have authored a few books on the subject, including a textbook (The Psychology of Human Sexuality) that is used in college classrooms around the world. I have a new book out today entitled Tell Me What You Want: The Science of Sexual Desire and How It Can Help You Improve Your Sex Life (https://www.hachettebookgroup.com/titles/justin-j-lehmiller/tell-me-what-you-want/9780738234953/), which is based on the largest and most comprehensive survey of sexual fantasies ever conducted in the United States. I surveyed over 4,000 Americans about their biggest sex fantasies. Tell Me What You Want looks at not just what we fantasize about, but where our fantasies come from, what they say about us, and how to talk to our partners about our desires.
