It's the reverse. Since the 60s and 70s and all the safe sex programs, we have far higher rates of STDs and abortions than ever before. When you tell a kid that, as you say, "Nothing is 100% safe but a hand job is safer than oral sex, oral sex is safer than intercourse, and intercourse with a condom is safer than unprotected intercourse," you are implicitly saying: Stay safe. Go out and give hand jobs and oral sex. All the articles mention that girls are giving oral sex so much because they've been taught that it's better and safer than intercourse. That is true. But it's ill-serving those girls.
I was never taught that. In fact, I've been taught the opposite. That the risk of transmission of STD's exists in both activities and you must be prepared to take that risk and be sure of the character and 'cleanliness' if you will, of the person with whom you plan to engage in any kind of sexual activity. There's being smart in having sex, then there's being stupid. You can make a choice...unfortunately, teenagers tend to make stupid choices. But they should be educated nonetheless by someone knowledgeable...be aware of abstinence, should they so choose to abstain from sex, but be aware as well of how to be as safe as possible when having sex.
