Pregnant Alba, 27, opens up about her sexy public image and how she finally learned to feel comfortable with her body, PEOPLE reports.

Public Image: "Hollywood always play[s] up your sexuality, because that's what gets men into the theaters. And I never really gave a s about all that stuff! It's nothing to be ashamed of. But it is definitely not what I am about by any means!"

Sexuality: "I don't think I was comfortable with my sexuality until I was an adult, probably, like, 22  that's when I stopped apologizing and stopped feeling ashamed. I did the Vagina Monologues in L.A. That made me proud."

On Sex Before Marriage: "I never believed women had to be virgins when they got married, or that a woman has to fall in love with a guy just because they're having sex. I don't think sex is a big deal. I hated the hypocrisy of it. Men can do whatever, and it's acceptable."
