Rebel Wilson didn't lose her virginity until she was 35.

The 44-year-old actress - who is engaged to designer Ramona Agruma and has daughter Royce, 16 months - hopes sharing her story will sent a "positive message" to others and reassure young people that "not everybody has to" have sex for the first time as a teenager.

She told People magazine: "People can wait till they're ready or wait till they're a bit more mature.

"And I think that could be a positive message. You obviously don't have to wait until you're in your thirties like me, but you shouldn't feel pressure as a young person."

The 'Pitch Perfect' star used to avoid discussing the subject as much as she could because she was "embarrassed" and didn't want people to think she was a "loser".

She said: "There was one vague time, I think I told my best friend, 'Oh, yeah, I just did it to just get it over with when I was like 23.' Just to really avoid the questions.

"Normally I would just leave the room when the conversation was happening.

"And then the people that said, 'Oh, at 24, it's so late.' And then I'm sitting here thinking, 'Oh my God, my number's 35. What the hell? I'm going to look like the biggest loser.'"

And though she considers herself a "late bloomer", Rebel believes if she was a generation younger, she'd have had a "very different" experience when it came to exploring her sexuality.

She said: "It's absolutely incredible, if I had been born 20 years later, I probably would've explored my sexuality more. I just knew I was attracted to men, and that was the normal thing.

"And so when I started opening myself up probably more after my father's death and realising, oh, even though I'd seen marriage as a terrible thing and waste of time, I started opening myself up to that.

"And then only years later, meeting women and having feelings for a woman, and that, I just think it's a sign of where society kind of was."
