Meant to say, I thought the advice was good: if your child tells you they've seen porn, don't get cross or agitated.
Try likening it to something as unreal as a horror film.
Make clear that what is on the internet is not the normal, loving relationships most people have but, but is showing abusive acts against women.
And do put parental controls on everything - pc, laptop, tablets, phones.
Have I missed any other good bits of advice they gave?
