Sex education should not be taught to young children, they are for the most part very young and innocent.  This is their time to be what they are, children.  I feel they have lifetime to learn about the birds and bees.  In 1920 the communist had a plan to take over the U.S. without firing a single shot and that was to get the chidrens minds off religion and get them thinking about sex.  Just look around you and you should be able to see how that is working out for our country.
