There is more than sex involved, but that was the biggest factor - at least in my experience which could well be different from typical.
I carefully avoided passing a moral judgement on their acts. However the fact is sex at 16 immediately jumps into moral issues (not just Christian - most world religions encourage marriage). I did my best those to focus on the fact that as a result of that choice they have eliminated their ability to get a head.
YOU are the one placing moral judgement on their choices and trying to make it look like my judgement.
Having a kid at 16 will screw you up. Most people have a moral objection to screwing up their life like that, as well as the practical objection. Most religions of the world have some form of moral objection to sex outside of marriage, it can be easily argued that the moral objection comes form the practical issues. (most religions predates any form of effective birth control. Today you can argue that the moral is obsolete)
Or put it another way, you cannot talk about kids having sex without everybody bringing their own different morals up. The two are very intertwined.
