The information age makes attempting to hide information on sex impossible  The internet provides a vast amount of easily accessible information about sex, of varying degrees of quality. Most children in the west now have access to the internet and are therefore likely to have access to this information on sex, or at least educational materials on sex even if the child’s access to the internet is controlled.  Given that it is impossible to prevent children from accessing this information if they really want to, it makes sense to present it to them in an organised and accurate fashion. Rather than allowing children to find information on their own through what may well be unreliable resources it is necessary that they should get good reliable information. That this information when there is safe sex education comes from the school means that the children know that they information is reliable. They can then use this information to help them decide how reliable any further information they may find from other sources is.
