The Gossip Girl actress said that her Catholic School education led to her seeing sex as something to be ashamed of, a belief that the 17-year-old had to work hard to overcome.
She told Grazia, 'I went to a super-repressed Catholic school. That was something I had to overcome actually. They really f**king make you feel like sex is wrong, but I think it's natural.
'My best friend's my vibrator. I don't date anyone, so why not? Guys can masturbate - why can't girls? I don't understand why it makes people uncomfortable. Sex is a part of life, it shouldn't be so scandalous.'
On the subject of her raunchy style, she added, 'My style's not for everyone, I'm an extremist. But my mum loves fashion, so she gets it.
'My dad is the one who introduced me to rock 'n' roll, playing me The Beatles and The Who. They know that sex and rock 'n' roll go together, you can't have one without the other.'
