UK sex ed for four year olds

It's vitally important that four year olds learn how to have sex without getting pregnant. The rate of unplanned pregnancy in the UK is precipitously high, with UK becoming known as the abortion capital of Europe.

The Family Planning Association, and Brook, both registered charities in the UK purport that the government isn't putting forth sufficient effort to educate kids about sex.
So look for this "solution" of making sure that pre school age kids learn these procedures early. It's much more significant for kids, (prior to the age of reason) than the time spent on learning to read, write and do the maths.
