Their findings are, in summary:
1 A significant proportion of children and young people are exposed to or access pornography;
2 Children and young people’s exposure and access to pornography occur both online and offline;
3 Exposure and access to pornography appear to increase with age;
4 Exposure is more prevalent than (ostensibly) deliberate access;
5 There are gender differences in exposure and access to pornography;
6 Access and exposure to pornography affect children and young people’s sexual beliefs;
7 Access and exposure to pornography are linked to children and young people’s engagement in “risky behaviours”;
Arising from this are several recommendations, mostly relating to the need for good education in sex and relationships.
I went to a conference on this subject before the report came out, and I was particularly struck by the remark of the presenter, who herself had a teenage son. He had expressed some interest in pornography, to which her response was: 'Do you really want to hand over control of your sexual life to commercial interests?' He later admitted that her remark 'had really killed it' for him.
