"A needed and timely defense of a necessary and timeless activity."
--Dan Savage, columnist of Savage Love and host of Savage Lovecast

"Chock-full of history, science, and Dr. Sprankle's characteristic humor, this book will inform, educate, and entertain you. Most important, from my vantage point as a sex educator and therapist, it will also put to bed all the historical and current falsehoods about masturbation that have too many people either trying to refrain or doing it with shame. Reading this book will set you free from unnecessary guilt about a natural--and pleasurable--human behavior."
--Laurie Mintz, PhD, emeritus professor at the University of Florida and author of A Tired Woman's Guide to Passionate Sex and Becoming Cliterate: Why Orgasm Equality Matters--And How to Get It

"Get out the lotion and tissues! Charge your vibrator! Masturbation is THE most frequent sexual behavior in humans. Across their lives, people masturbate far more frequently than they have partnered sex. Dr. Sprankle dives, umm, headfirst, into what we know about erotic self-pleasure, exposing all of the dirty secrets about masturbation that THEY want you to not know about. This is THE book to keep on your nightstand. Seriously."
--David J. Ley, PhD, sex therapist and author of The Myth of Sex Addiction

"DIY: The Wonderfully Weird History and Science of Masturbation is equal parts fascinating and fun. Sprankle serves a perfect blend of history, research, and clinical insight that debunks some of the wackiest myths and misconceptions about self-pleasure. Readers will walk away informed and empowered--and able to take their sexuality in their own hands."
