A new report claims that half of UK secondary school teachers do not feel confident about delivering lessons regarding sex and relationships.
The survey, published by the National Society for the Prevention of Cruelty to Children, (NSPCC) and teachers union NASUWT, also shows most teachers want more training before leading lessons on the subject.
The report was published following the emergence of Everyone Invited, a website that allowed student victims of sexual assault to share their experiences anonymously, whilst stating the school that they attended.
It's been a year since lessons on sex and relationships were made compulsory in England.
For some Christians, the thought of their children receiving sex education lessons outside of a home or faith setting raised concerns about eliminating traditional Christian values.
Steve Beegoo, head of education at Christian Concern and CEO of the Christian Schools Trust, said to Premier: "Many Christian parents that I that I talked to, can't believe the speed at which the state and the government have taken over this area, saying 'Well, it's our responsibility, and we should be teaching them this, that and the other.'
"Whereas, as Christians, we understand we're supposed to be training up our children and the way they should go, and when they're old, they won't turn from it.
He continued: "It's a real responsibility for parents supported by the church community and the youth leaders to be able to speak primarily into the subjects.
"The secondary schools should be a secondary, ancillary thing that the schools are doing so actually, Christian parents, Christian communities and churches should be taking up that baton that the Lord has been Lords given to us in terms of responsibility for our children."
