"But she knew how to get pregnant when she did it. She made a decision to ignore the risk and do it anyway. Why? She wasn't taught to say "No"."
Actually, according to many repeated sex surveys of teenagers, there are still teenage girls who think "I can't get pregnant the first time!". Your assumption of "She knew how to get pregnant" is sadly naive.
Teenagers are stupid. We should try to remember how stupid and naive we all were at 14-16.
I was taught abstinence. Growing up in a strict Catholic family, I had no other education than abstinence, except for some "Horrible Results of VD" film in high school biology. But when I "fell in love" at 17, all that flew out the window. Luckily, no teenage pregnancies resulted. But my religious upbringing was no match for my hormones.
Abstinence is nice...it's just not very grounded in reality...the 'reality' being that teens throughout history have had sex, despite the best intentions of prevention by their elders.

I'd use the word "ignorant" instead of "stupid." It's important to teach them things, so they won't be ignorant any longer. That's the point that seems to be missed.
I doubt seriously anyone actually believes that in 2006 but odds are that belief is somewhat true. The chances of "catching" during a single event are small. Very few people get pregnant just having sex one time. They are usually having sex and WHOOPS. Law of averages catches up.
