As the previous 30 years of sex education in the US has shown, teaching about birth control has done little if anything to slow down the rate of teenage pregnancy. If kids DO use birth control at all, they aren't consistent about it, which has the same effect as not using it at all.
All that govt.-school sex education has mainly hyped the sexual desires of the young and informed them in great detail about every sexual practice and orientation, while indicating that all were equally valid choices and that kids should simply be “ready” and practice “safe sex.” We now have oral sex being regularly indulged in by kids of 12 or so. I would bet that millions of adults in previous centuries never experienced that in their entire lives, yet never felt unfilfilled or deprived.
