At one school in London, they're dealing with the issue of online porn and the impact it can have in relationships and real life.

A group of of 17-year-olds are taking part in activities to learn the difference between porn and reality.

But the National Union of Teachers (NUT) says referring to porn in lessons is a step too far and should only be discussed if students approach it.

The Department of Education won't go into details on porn lessons but say it is up to schools to work with parents on what sort of sex education they deliver.
