More like a poor analogy.
The average 13-year-old understands the basics of human reproduction and knows how to have sex. That really has nothing to do with whether they are competent to make adult decisions and whether they understand all of the ramifications of a pill that apparently has no long-term studies indicating possible effects of the pill. In fact, a I doubt a 13-year-old can legally provide informed consent without the parents' involvement.
We really have a contradiction in our society, because we have said, in every state, that 13-year-olds cannot consent to sex, but we allow those same 13-year-olds to get abortions and take these kinds of pills without parental involvement.
She is having sex with same guy. In that sense she really isn't much different than the likely millions of women who have used the morning after pill more than once.
These girls and boys needs to be taught sex ed. Something to balance out whatever they get from watching TV and reading mags. And I'm not talking porn here. The superficial image of relations as a whole, somewhere, some balancing has to be offered.
I remember my sex education. It didn't made me want to have more sex, it was all about the different STD's that are around, and how dangerous it is to have unprotected sex.
If anything, it seems like it may be too much of a trouble for teenagers to get pills and condoms, and when the sex occurs, they don't have protection, and will foolishly opt for Morning after pill instead.
Which is better than regular birth control, but does nothing to keep STD's at bay.
Some people believe that if you don't talk about sex ed, don't give out condoms, and don't offer abortions, promiscuity among teens will vanish.
That is not my belief.
