Taylor Momsen was made to believe sex "was wrong" when she was at school.
The singer-and-actress - who began modelling aged just two years old - had a Catholic education and admits sex was rarely discussed but she believes everyone should be open about their urges and desires.
She said: "I went to a super-repressed Catholic school. That was something I had to overcome actually - they really f***ing 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."
Taylor, 17, also insisted her parents are not concerned about her wild behaviour and provocative image.
She added to Britain's Grazia magazine: "My style's not for everyone - I'm an extremist. But my mom 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."
