Is sex education compulsory in UK primary and secondary schools and are children taught about porn, sexting and masturbation?
SECONDARY school pupils will be given compulsory sex education classes including subjects such as sexting and revenge porn in radical changes.
Children will also receive lessons on healthy relationships from the age of four from next September after the then Education Secretary Justine Greening said the current curriculum had become "outdated".
How will the changes impact current sex education in schools?
Reforms will see relationship and sex education made compulsory for all secondary-age pupils, while primary schools will be required to teach children about relationships from the age of four.
At present, sex education is compulsory only for secondary pupils in schools run by local authorities.
The reform will make it mandatory in all schools, including academies, independent schools and religious free schools and extend the subject to include relationships as well as modern phenomena such as internet porn and sexting.
Four-year-olds will also learn the importance of not cuddling strangers, it was revealed.
Greening had previously said that any education will be "age appropriate" and it is not expected that children as young as four would be taught about the biological mechanics of sex.
Instead, they are likely to be taught about relationship issues.
A Downing Street spokesman said: "Relationship and sex education is clearly an important part of preparing children and young people for adult life."
What will children be taught about porn and sexting?
Greening said children should be taught about the dangers of sexting and porn to address concerns about the rising number of children sending indecent images.
Sexual consent and domestic violence are other topics that should be taught in sex education lessons, her department was told.
Schoolchildren will also be taught about consent and peer pressure - in both the online and real worlds.
Other areas that schools will cover include the laws around sexual exploitation, abuse, grooming, harassment and domestic abuse.
The Education Secretary Damian Hinds said in July 2018: “This guidance was last updated before the children who are at school today were born and, while many schools already choose to teach young people about the importance of healthy relationships, this updated guidance will support schools as we make relationships education compulsory.
“This new guidance will ensure lessons teach children and young people how to recognise when someone else has not given consent and more importantly why they should not to put pressure on someone else to do something they don’t want to.”
A sex expert wants masturbation taught to 11-year-olds in schools.
Speaking on This Morning in September 2018 Nadia Bokody said: "I think the benefits of masturbation are really around creating a lot more body autonomy - particularly for young girls.
"There's so much stigma and mystery surrounding women body parts. By acknowledging masturbation is essentially taking that bit of taboo away."
