Firstly Gender

I forgot to mention what gender you are. It may have seemed obvious since you are a princess but not so since you are part dragon. Between your legs is a small pink slit inside is a vaginal opening so you are definitely female,...right?

Well, you grew breasts so you are at least partly right but you are also a part dragon and some male dragons conceal their genitals in a slit-like sheath so there could be a cock there as well.
