I still don't agree with this. There are a million and one reasons to wait, even if it's not waiting until marriage and just for emotional maturity and a little bit of common sense.

Now, I don't think you can say that those kids shouldn't have waited. Believe it or not, "I don't want to get pregnant" is a reason that some people use when they're still living with their parents to delay having sex. This is not the "result of [thousands] of years of narrowminded cultures ... trying to suppress women's sexual desires," this is a little bit of reason in a child's mind. When they hit the age of consent, fine. But no one, by reason alone, should have sex until they have the common sense to be careful about it. Again, reason. Not religion.There are substantial differences in fertility statistics and behavior between women aged 18-19 and those aged 15-17. In 1996, approximately 880,000 pregnancies occurred among U.S. women aged 15-19 (Table 2, page 276): about 543,000 among older teenagers and 338,000 among younger ones (not shown). In addition, 25,000 pregnancies occurred among women younger than 15.
