If sex education in schools traditionally meant teaching the biological ‘facts of life’, today it is far more comprehensive, having been rebranded ‘sex and relationship education’ (SRE). As well as supposedly reducing the likelihood of unwanted pregnancies and sexually transmitted diseases, SRE is increasingly seen as a means of helping young people deal with the emotional turmoil, hurt and confusion that sometimes comes with sexual relationships. But can relationships really be ‘taught’ at all? Is it the job of schools and teachers to tell young people how to run their private lives? This excellent debate, filmed at the Battle of Ideas gets heated.
