In Britain, teenage pregnancies and sexually transmitted diseases are among the highest in Western Europe.
Sex In Class, a new Channel 4 documentary, shows how one Lancashire school tackled the issue, by calling in Belgian sexologist and US Goodwill Ambassador Goedele Liekens. She takes on a class of 15 to 16 year olds, finding out their views on sex and teaching everything from porn to sexual pleasure. Her aim is to turn her unorthodox lessons into an official GCSE and in the documentary we see her meet teachers and MPs and try and get them on side.
Goedele joins us in the studio today to talk about her controversial teachings.
