In Puppet on a String, a Barnardo's report on their work with young people in London, it was stated that the peak age for young people to be sexually exploited was 15 - but children as young as 10 were identified as being at risk. 

 

Girls and young women were more than six times as likely as boys and young men of being at risk, but it was widely understood that actual risks to males were probably underestimated.
