The don't date until 16 isn't really like something that would keep you from your salvation, it's more of a suggestion. The main problem with getting serious with someone young is there's more of a chance that the individual will have sex earlier in life, before marriage. I saw a study on that and while obvious waiting until you're 16 to date or dating before as an early teen isn't going to guarantee that is the way it'll be, but it definitely helps to just wait. And we believe in being chaste, so obviously this is very important to us (I'm sure you knew from Eclipse and BD haha).
My parents never really talked to me about it. I decided to listen to the advice of our leadership. Of course, if I had decided to date before I was 16, I don't know what my parents would've said.
