NEARLY one in 10 children between the ages of 12 and 13 fear they are addicted to porn, according to a new poll.

The survey of nearly 700 12-13 year-olds in the UK, including 118 young people in Scotland, also reveals that that around one in five said they'd seen pornographic images that had shocked or upset them and 12% admitted to making or been part of a sexually explicit video.

The NSPCC's Childline service has launched a campaign to raise awareness and provide advice to young people about the harmful implications of an over exposure to porn.

The ChildLine FAPZ campaign (the Fight Against Porn Zombies) will use a series of animations looking at the implications of over exposure to porn on both boys and girls.

The animations then link to a range of information and advice, to help young people understand the implications associated with replicating pornographic content in real life situations and to protect them from putting themselves in potentially risky situations.

Elaine Chalmers, ChildLine Scotland area manager, said: "Our young people can access a wide range of online porn, far more easily today, than they could even a couple of years ago. And as porn becomes more normalised, young people's understanding of what a healthy relationship looks like becomes increasingly skewed.

"Contacts to ChildLine about porn have doubled in the last year.

"Discussion threads on our website message boards with porn in the title are viewed over 18,000 times per month.

"Young people who talk to us about porn tell us that it can make them feel depressed, insecure about their bodies and that it impacts on their self-esteem. Young people also tell us that porn is teaching boys that girls are for sexual gratification and girls that they must look and perform like 'porn stars' to be liked and valued by boys."

Dame Esther Rantzen, the Founder of ChildLine said: "It is shocking that children as young as 11 are contacting ChildLine with concerns about porn. Young people are turning to the internet to learn about sex and relationships.

"We know they are frequently stumbling across porn, often unintentionally, and they are telling us very clearly that this is having a damaging and upsetting effect on them.

"Girls in particular have said they feel like they have to look and behave like porn stars to be liked by boys.

"We absolutely have to talk to young people about sex, love, respect and consent as soon as we feel they are ready, to ensure that they gain a proper perspective between real life relationships and the fantasy world of porn."

In 2013/14 a report by the charity ChildWISE revealed the website Pornhub was named in the top five favourite sites by boys aged 11-16.

A young boy aged between 12-15 years-old who contacted ChildLine Scotland said: "I've been comparing myself to the men in porn films which has started to make me feel really insecure. I feel weedy in comparison to them, so I'm embarrassed about my body.

"Some of the things they do in the videos makes me a little uncomfortable but I can't help watching."

Laura Tomson, co-director at Zero Tolerance, a Scottish charity working to tackle the causes of men's violence against women supports the ChildLine FAPZ campaign. She said: "These findings confirm what we know from our work with young people in Scotland - many are exposed to pornography from a young age and feel pressured to conform to its sexist, harmful representations of sex."
