Teachers are warning that young people are being damaged by an over-sexualised culture.
The National Union of Teachers annual conference will hear claims sexism is being "rebranded" as something fashionable and mainstream.
Delegates are to criticise the "raunch culture" of lap-dancing clubs and pole dancing.
Teachers, meeting in Liverpool, say it can have a "disastrous effect on the self-image of girls".
The National Union of Teachers will hear warnings from teachers that "sexism and inequality are still a huge factor in shaping women's lives".
The conference will hear claims that old-fashioned sexism has not gone away, but has been re-invented into something that appears to be "ironic or empowering".
Teachers will warn that pole dancing clubs and beauty pageants are turning back the clock on decades of campaigning for sexual equality.
There will be concerns that pupils are growing up in a culture where pornographic images are widely available, cosmetic surgery is advertised and there is a "fixation" with staying slim.
Teachers fear this can undermine young women's self-confidence and contribute to problems such as eating disorders and anxiety about their appearance.
This can disrupt both girls' school work and their social life, say teachers.
The motion to be debated on Monday afternoon will say that: "Growing up in a world where it is normal for women's bodies to be seen as sex objects affects the way that girls in our schools grow to view themselves and their place in society."
There will also be claims that this is linked to the number of sexual assaults and incidents of domestic violence.
Delegates will call for recognition of the negative impact of sexism and the need to protect equal rights for women.
End Quote Christine Blower NUTIt is important for all children and young people to learn, in an age-appropriate manner, about respect for their own and other people's bodies and emotions"
In an earlier debate on the conference on Sunday, teachers described the problems of young people living in an environment with such widespread access to pornography.
A teacher from east London talked of pupils setting up websites showing sexual images of teenage girls in their schools.
Last week, the Association of Teachers and Lecturers' annual conference also heard warnings of pupils viewing aggressive sexual images.
Teachers said they feared pupils could be "desensitised" by such images and called for more guidance on how schools should tackle such an over-sexualised youth culture.
Even very young children were inadvertently exposed to such images, the ATL conference heard, either by watching video games with older children or watching late night television.
Teachers said that they had heard sexually explicit language from young children.
NUT general secretary Christine Blower said: "It is important for all children and young people to learn, in an age-appropriate manner, about respect for their own and other people's bodies and emotions.
"This is all the more important given the rising levels of pornography which is very much in the public domain. There also continues to be a high rate of sexual harassment and homophobic bullying in society at large, despite efforts in schools to address and reduce it."
