Natural phenomenon...girls always mature before boys!
That happens because girls go through adolescence before boys do...I honestly don't know why, but that's what happens.
Because when boys develope and stuff all they think about is women and getting into other girl genes and that is bad. Girls don't really think in that kindda way unless they been raised by demons or something
Good question. I don't know. It is probably because girls have more through go through like periods etc
