The bottom line: Sex Education isn't as extensive in schools as it needs to be, and adults who believe otherwise are the ones who think teaching only abstinence is realistic. Most school boards have maintained the same sex education program that they began 20+ years ago and although it has advanced slightly, kids are still being taught the basics; how babies are made, instead of std risks and realistic pregnancy prevention. Parents are upset when kids get condoms from schools because it "promotes sexual activity" but those children would discover sex themselves eventually anyway. Parents can't say they want their children to be ready for sex instead of getting the idea from an educational setting but it's been my experience that despite all the mental preparation, parents are rarely ever completely accepting of their child's sexual activity.
A more extensive sex education program would show kids that there are other ways to prevent pregnancy and how important it is to be safe, aside from abstinence. Kids can either be safe and smart, or dumb and at a constant risk. School children, especially in High School, aren't really worried if that hot guy or girl they have a crush on has gonorrhea; but a more encompassing and encouraging sex education program could teach them how to be cautious and continuously aware. It's infuriating how some adults think their kids will learn all they can from friends, or television; and while it's true that they will learn some things, they won't be educated about everything sex-related. Adults should be more considerate of their teens budding sexual curiosity, and encourage them to be educated while asking important questions in a safe environment.
Ultimately, more extensive sex education can save lives and prevent a number of pregnancies. As parents, we try to teach our kids the very best in morals and beliefs, but in the long-run their decision to be sexually active and scaring them into abstinence through our school systems isn't the solution.
