Just some additional info about this:
From my point of view, sex education is very essential as young as we are right now so that we would know more and more about the disadvantages and advantages we get from it and to avoid further complications in the future. Since we all know that it's mainly for the future, some are entering into such situations, that's why students should be taught and informed about it because this is no laughing matter nor is it "just for pleasure" only. Open-mindedness is also a very important word and action to be used at all times.
Hope this helps even though I'm late ^_^
