Me [25F] with my boyfriend [26M] of 1 year. He uses the same two nicknames for his sister [17F] and I. Is it unreasonable of me to not like that?

He has a variety of things he says to me, most are generic "beautiful", etc., pet names, but the ones he uses the most, and the ones I like the most are "little Pinocchio" and "little Chinese girl" (chinita, in Spanish, it's a common term of endearment for actual SE Asian-looking people like me, or people who randomly have those almond-like "Asian" eyes, like his sister).

The thing is, he's clearly been using those nicknames for his sister for far longer than with me, so it would be pretty ridiculous of me to ask him to stop using them for her. Pretty much everyone in his family knows his sister as chinita or just china or la china (Chinese girl, the Chinese girl), but only he calls her little Pinocchio (and only he calls me those two nicknames).

I have my own unique nickname for him and I'd rather have a unique one from him. Is it unreasonable that I would want this? I don't know why I don't like sharing the nicknames but I simply don't. I feel a little stupid asking help for this, it seems like such a little thing to be unsatisfied about, and that's kind of the reason I don't to ask anyone personally about it.

Is it normal that I don't like sharing the nicknames? What should I do about it?

tl;dr: BF uses the same two nicknames for his sister and I and I don't like it. What should I do about it?
