Jennifer Lawrence admits filming her first-ever sex scene left her feeling “vulnerable.”

The Oscar-winning actress opened up about the experience, which she deemed “weird,” during The Hollywood Reporter‘s 2015 Actress Roundtable.

“I had my first real sex scene a couple weeks ago [while shooting Passengers with Chris Pratt], and it was really bizarre,” Lawrence revealed.

While Lawerence, 25, said that “everything was done right” on the set of the romantic sci-fi drama it was still a “bizarre experience.”

The other actresses who chatted with Lawrence included Cate Blanchett, Jane Fonda, Brie Larson, Helen Mirren, Charlotte Rampling and Kate Winslet. During the extensive round table they also opened up about gender equality in Hollywood, something Lawrence addressed in her October wage gap essay.

“There’s always a backlash in everything that you do, but it’s not going to stop or change anything,” she said. “And it’s not only an issue in Hollywood. When you’re asking about roles for men and women, men certainly have a longer shelf life. Men can play the sexy lead for 20 years longer than we can … Across all fields, women are generally paid 21 percent less than men.”
