Children as young as five are being exposed to “shocking” sex education materials in primary schools, according to research.
A report published on Wednesday claims that schools across England are using books that cover subjects such as orgasms and foreplay.
The study, by the Christian Institute, found a range of local councils recommended titles for use in primary sex education lessons that contained highly explicit references.
One book for children aged just five contains cartoon images of a couple having sex and another compares sex to skipping.
