Uhh...no, I'm pretty sure you get a male dragon whatever it is.
I'm a girl, and my dragon isn't a girl. I'm not sure what you mean
by getting the girl dragon.
If you mean the 'pretty flowery rainbow explosion one' like
Sepulchre got when his Dragon Egg hatched, no, you don't. You can
customize your dragon if you have a Dragon amulet though...
