21-year-old Sophiie Turner was cast as Sansa Stark on Game of Thrones when she was just 12 years old.
The show later premiered when she was 15.
In an Interview with The Times, she explained how her script turned out to be her sex education.
She said, ‘I’d be doing a read-through and we’d be talking about very graphic stuff. The first time I ever found out about oral sex was from reading the script.
‘I was like … Wow! People do that? That’s fascinating. I guess that was my sex education. Being on Game of Thrones.’
