Pornography made my boyfriend abuse me, says teenage girl

A tenth of 12 to 13-year-olds are worried they are addicted to pornographic material according to a new poll by the NSPCC.

Nearly 700 people in that age group were surveyed - 12 percent of them said they had taken part in a sexually explicit video.

Experts say it is partly down to being able to easily access such material on tablet devices and smart phones.

The Today programme's Sima Kotecha spoke to one young woman who said her boyfriend's pornography habit when she was 13 contributed heavily to him abusing her.
