Sexual exploitation of children and young people under 18 involves exploitative situations, contexts and relationships where young people (or a third person or persons) receive ‘something’ (e.g. food, accommodation, drugs, alcohol, cigarettes, affection, gifts, money) as a result of them performing, and/or another or others performing on them, sexual activities. Child sexual exploitation can occur through the use of technology without the child’s immediate recognition; for example being persuaded to post sexual images on the Internet/mobile phones without immediate payment or gain. In all cases, those exploiting the child/young person have power over them by virtue of their age, gender, intellect, physical strength and/or economic or other resources. Violence, coercion and intimidation are common, involvement in exploitative relationships being characterised in the main by the child or young person’s limited availability of choice resulting from their social/economic and/or emotional vulnerability.
