I'm was a late bloomer/young looking for my age/shortie. At 15, I hated it. At 32, I love it. What better excuse to go over and talk to that cute guy then to ask him to get you something you can't reach? (Not that I ever do that anymore. . .
) One advantage too, is that any guys who show an interest probably actually are interested in
you, not your blooming body. Now is also a good time to foster other talents to boost self your esteem. "I may not be hotter than 'her' but I can outrun/outswim/get better grades/draw better" etc.
Good luck!
