A poll of over 2,000 14-18 year olds by Research Bods found 78 per cent didn't have the chance to influence the content of sex education, while 72 per cent said they felt they should have the opportunity to.
Twenty two per cent admitted the sex education they had received in school was poor, or very poor, and more than half said relationships were not discussed, and neither were emotions.
The Government is now reviewing how sex education is taught, as just 13 per cent of teens said they learnt sex education through school, and 36 per cent said they got the majority of information from friends.
A spokesman for the Department for Education said they were reviewing they way the personal, social, health and economic curriculum was taught:
'We are simplifying the statutory guidance on sex education to focus on relationships, positive parenting, and teaching young people about sexual consent.
'We have launched a public call for evidence - and will consult on firm proposals in due course.'
Do you think teenagers should be more involved in the way sex education is taught in schools?
