"As a young woman you don't learn how to pleasure yourself, you don't learn what an orgasm should be, you don't learn that you should have feelings of satisfaction," she says.
Woodley is no stranger to talking about sex. The actress got her big break playing Amy Juergens on ABC Family's The Secret Life of the American Teenager in 2008, but says her concern with women's sexual health inspired by her role as a pregnant teen. In fact, writing about masturbation has been a lifelong "dream" for the Snowden star.
"I've always had a dream of making a book called There's No Right Way to Masturbate," she shares. "If masturbation were taught in school, I wonder how [many] fewer people would get herpes aged 16, or pregnant at 14?"
While she certainly advocates for masturbation, Woodley recently credited a different kind of "self-love" for getting her through her "teenage crises."
"One day I was having one of my teenage crises, when you think everything's falling apart -- your estrogen and progesterone are freaking out," she told Elle last year. "And [my grandmother] said, 'Shai, the most important thing in life is self-love. You've gotta take care of yourself. You've got to take care of yourself, and you gotta live from your deep heart.'"
