After nearly 25 years in Hollywood,Natalie Portmanhas a unique perspective on the dangerous machinations of fame.

It’s a subject central to hernew film,Vox Lux, in which the actress, 37, plays a troubled pop icon who survived a childhood trauma that launched her career.

“She is such a wild character, but she’s also someone I felt was a real person, who is the product of this life that has happened to her,” Portman tells PEOPLE in the magazine’s new issue. “You see in this film how a young girl is packaged into this brand, and it’s kind of separate from her. I experienced a different degree of it, in a different way, and obviously I have very different support system than the character in the movie, but you see what the culture wants from you, or demands from you and wants to put out there.”

For much more on Natalie Portman andVox Lux, pick up the latest issue of PEOPLE.

“I understood very quickly, even as a 13-year-old, that if I were to express myself sexually I would feel unsafe and that men would feel entitled to discuss and objectify my body to my great discomfort,” she said. “I felt the need to cover my body and to inhibit my expression and my work in order to send my own message to the world that I’m someone worth of safety and respect.”

Years later, Portman has come to terms with the situation. “I know I was sexualized in the ways that I was photographed or portrayed, and that was not my doing,” she says. “That becomes a part of your public identity.”

Portman says the pressure of being in the spotlight is particularly intense for young women trying to figure out who they are vs. who others want them to be.

“It’s complicated to have your own private development and maturation alongside that [pressure] as a person, kind of having these double identities,” says Portman. “And I think that it’s a big conversation about how many different kinds of things girls and women can be.”

Vox Luxis now playing in theaters.
