Jameela Jamil finds out if it's true that children are being exposed to more pornography than ever before - and what the effects of that might be. With smartphones and tablets making it easier than ever to get hold of the most explicit images, there are fears that each generation is seeing porn earlier than the one before, so Jameela meets teenagers across the country to hear from them what impact it has had on their attitudes and behaviour. With an exclusive survey, the biggest of its kind, revealing the truth about how much porn kids really see, she also talks to those behind some of the mostly commonly viewed material, including one of Britain's best known porn stars and rap artist Skepta, to see if they are worried about who's watching. She visits a family whose eight-year-old son was unexpectedly exposed to hardcore porn and, as she hears how it has directly affected people's lives, Jameela asks if teaching children about porn could be the answer - and if so, at what age that should start.
