Secondary school pupils will be taught about the difference between rape and consensual sex from the age of 11.
The lessons, which could be introduced in April, will be based on a series of resources being developed by the Personal Social Health and Economic (PSHE) Association.
The proposals have been given the backing of Education Secretary Nicky Morgan, who wrote in The Sunday Times: "We have to face the fact that many pressures girls face today were unimaginable to my generation and it's our duty to ensure that our daughters leave school able to navigate the challenges and choices they'll face in adulthood.
"Our commitment to supporting women should start long before they take home their first wage. We have to ensure that the education girls receive not only allows them to reach their academic potential, but also prepares them for life in modern Britain."
The recommended resources, which Mrs Morgan has stressed will be age appropriate, are said to be aimed at giving teachers more confidence and better guidance to teach difficult subjects.
Children will be taught how to respond to sexual pressure as well as ways to deal with sexual coercion and manipulation.
Drop boxes will also be placed in classrooms so pupils can post questions anonymously.
But the Education Secretary stopped short of making the proposals compulsory, leading to claims that many schools will simply ignore them.
A spokesman for the PSHE described the Government's response as 'surprising and deeply disappointing'' and accused the Government of 'saying nice things but not making a meaningful change'
He added: "As an expert body, we can produce guidance like this for teachers, which we think reflects leading practice on teaching about issues like consent.
"But, if the government is serious about tackling issues like child sexual exploitation, they need to ensure that this subject is taught in every school and by trained teachers."
