Despite decades of medical and psychological research confirming that masturbation is healthy, the act remains shrouded in taboo and pseudoscience. In DIY, Dr. Eric Sprankle reveals the untold story of crusaders on a long campaign to suppress masturbation and the sex educators fighting back with science. He introduces readers to a colorful cast of characters: doctors advocat­ing for the use of chastity devices, wellness influencers who believe ejaculation depletes the body of vital nutrients, pastors who preach that masturbation creates mermaids, and vibrator aficionados who teach the curious how to come. DIY will challenge what you think you know about the very human need for self-pleasure. Trade Paperback Book; 5 1/2 x 8 1/4 inches; 240 pages.
