How much should children learn about pornography?

The prevalence of the internet on tablets and phones means many children are only a click away from seeing inappropriate or explicit material online.

Sexual and violent imagery can be upsetting and damaging for young people, so how best to educate children about what they might see?

BBC Breakfast presenters Charlie Stayt and Naga Munchetty spoke to presenter Jameela Jamil and sex education teacher Lynette Smith who were involved in a BBC Three documentary Porn: What's the harm?

Porn: What's the Harm? is broadcast tonight 10 April at 2100 on BBC Three
