>>40099109I'm 36, my puberty started at 11, by 16 I could grow a decent beard, but it took a couple more years for it to become a proper full beard. And that's normal for my entire class, well, almost, we had one late bloomer who started in highschool, literally at 15 or so, the contrast between us and him was insane.
And yes, girls start at 9-10, it's pretty normal, iirc, puberty for black girls can start as early as 8 and it won't be considered precocious.
