Why do we have a type?

I really hate the fact I have a heavy attraction towards blonde blue eyes pale skin woman and how my chances of being with one equals to a black hole sucking our reality.

I don’t understand why, everything started way before Disney became a thing and the worst part is I have already tried to feel attracted towards other races but not luck at all.

Am I just inexperienced in love and I just need to find someone that changes my perspective or is this just the way we are build?
