Scarlett Johansson is a superhero (currently filming the latest installment of The Avengers), a mom (to 3-year-old Rose), and a fierce feminist. When it comes to women’s health and sexuality, the 32-year-old star tells it like it is. And the way she sees it, even though we’re having a sex-positive moment right now—with a slew of startups dedicated to the happiness of your lady parts—Johansson says there’s still way too much shaming going on. And she’s not having it.

“When women talk about enjoying sex, it’s almost forbidden. Just having a healthy sexual attitude, you are labeled as loose, wild, a slut,” she tells Cosmopolitan. ”

“The minute you talk about enjoying yourself, being curious, that is still taboo.”

You have no morals, and you’re seen as some kind of sexual deviant or someone who can’t be in a monogamous relationship. The minute you talk about enjoying yourself, being curious, that is still taboo,” she says.

Another thing Johansson is passionate about? Health care for women. “There’s no reason we shouldn’t be talking about our reproductive rights,” the longtime Planned Parenthood supporter says. In another Cosmo article last year, she recalled visiting the clinics as a teenager, saying, “All my girlfriends did—not just for birth control, but for Pap smears and breast exams.”

And she’s not afraid to put her status as Hollywood’s highest-grossing film actress of all time on the line to defend the politically besieged nonprofit. “I grew up in an environment that encouraged activism, so I never thought about the effect that it would have on my career at any stage.”

Considering that people who feel a sense of purpose tend to live longer (and sex is a major stress-reducer), sounds like Johansson is setting herself up for a healthy, loud-and-proud life. Want to bring out your own inner activist? Here’s how.
