It's a shame that modern society fails to teach principle and only attacks actions. Sex isn't something to be ashamed of, but extreme liberalism is no better than extreme conservatism. The problem isn't that kids suddenly have sex drives, it's that they aren't being taught how to become mature adults capable of handling these situations, so sex becomes a public "crisis" at early ages when it shouldn't really be.
Condoms may prevent unwanted pregnancies and disease, but it doesn't make a person a strong individual. In fact, I would argue that the concentration on simply avoiding pregnancy and disease somewhat hinders the development of good morals and ethics. Some may laugh at this perspective, but in the middle school setting, and rather most primary levels of education, the focus should be on building strong individuals who are capable of handling these situations without the school having to play the role of parents.
I don't argue that condoms and proper sex education are unnecessary, I just think that more focus is being placed on sexual activity as just another "thing you do" than a more mature activity that requires responsibility. Again, prophylactics alone do not create a responsible adult.
Most of the blame in my opinion is on the parents for not instilling proper behaviors, but certainly the schools seem to miss the mark in their attempt to make up for a lack in family values. Although technology is slowing removing the risk of unwanted pregnancy, I feel as if the primary biological purpose is still procreation, and that young kids shouldn't be having sex until they're capable of making wise decisions (including the possibility of supporting a family; accidents happen). That just doesn't occur very often at the middle school level.
