London, July 5 (ANI): Parents in the UK are up in arms after two health charities called for compulsory sex lessons for kids as young as four.

The Family Planning Association and Brook, which runs advice clinics, say that kids should be taught the names of genital organs and the basics of sexual relationships.

This, they believe, will cut down on the numbers of pregnant teens, as well as sexually-transmitted diseases.

Parents however, are not impressed. And joining them in their ire are childrens groups, churches, and MPs, reports The Sun.

Campaign group Kidscape branded sex lessons at four daft, while Tory MP Douglas Carswell said: It would be an outrage and most parents would find it abhorrent. Its a crackpot idea.

A spokesman for the Bishop of Lichfield, the Rt Rev Jonathan Gledhill, said that sex lessons at four would only make teens eager to experiment.

At such a tender age, children should be encouraged to act like children, he said. (ANI)
