Sex education: Too much too young?

File on 4 investigates claims that children are being taught graphic and age-inappropriate material as part of their Relationship and Sex Education.The government has brought forward a review into how sex education is taught in schools in England following concerns that children across the country are being taught lessons on oral sex, how to choke your partner safely and 72 genders as part of their RSE.We speak to teachers, parents, children and sex education providers to try and discover what's really happening in schools and where there are instances of bad practice, we ask if they're part of a systemic national problem in sex education or extreme examples used to push a political moral agenda.Reporter: Kate West Producer: Hayley Mortimer Researcher: Shona Elliott Technical Producer: Richard Hannaford Editor: Carl JohnstonArchive credits: This Morning, Good Morning Britain, TalkTV, GB News, Life Begins, Huntley Film Archives
