Liz Walker was only six years old when an older girl from up the street squashed in next to her on the school bus and excitedly whispered "Hey do you want to see something?" It was a magazine she found under her brother's bed and full of graphic pornography.

"I felt this sense of disgust, but also arousal," Ms Walker remembers. "I was catapulted into an awareness of my sexuality I wasn't ready for. In my six-year-old brain I though that's what you had to do to get noticed."

She started looking at porn every afternoon after school, and trying out the scenarios she saw on other children. Her early sexualisation saw her lose her virginity at 12 and have multiple sexual partners during her teens.

"I was seeking out those sexual interactions wherever I could because I had been conditioned to think that's what women did," Ms Walker recalls. "I had a reputation as a slut from a very young age."
