As I recall, (it was a very long time ago that I was a teen) us gals had a certain aroma about us at that age too. Boys ( and I suppose some girls) found it intoxicating, the rest of us took it as time to introduce our friends, daughters, nieces to deodorant!
Yes, they mature as they get older, but only in some ways. The fist bumping, high five, physical shows of affection don't go away. My dad used to say growing old may be manditory , but growing up is optional.
