I'm scared that my sexual preferences could be deemed as racist!

I apologise if my thread sounds very provocative, but these are my genuine feelings. I am not all racist. I view people beyond the prism of skin colour, which I believe has been accentuated by my bi-racial background. However, this has not really prevented me from forming what some may deem "politically incorrect" preferences in partners.

I'm 18, and half Asian (primarily Chinese) and half white (Italian and Jewish), a "hapa". My overwhelming preference for women is East Asian women. I don't know why but I just seem to gravitate more towards them, and the feeling seems to be mutual. A lot of Asians say they like my really pale skin and height, in addition to my obviously Eurasian looks. I've been told that I do look like a perfect blend of my racial components- tall, pale, sharpish nose, and somewhat "Asian eyes".
But, I find it very hard to form an emotional rapport with them. Beyond the superficial, I find it difficult to actually "like" them, without knowing them for continuous periods of time. I guess the culture clash thing doesn't help- I'm very westernised, culturally, although I am becoming increasingly interested in Asian cultures.

However, I literally can't get attracted or aroused by any other ethnicity. Though I can get emotionally attached more easily with a non-asian woman. This is, indeed, a core component of a relationship, but I fear not being physically attracted to them would hinder any chances of having said relationship.

Regarding men, I am far more open. I seem to be far less superficial, with regards to race. I find physical attraction far easier, and I take into account personality a lot more. I guess I must be doing so subconsciously.

I am scared that my preferences may hurt my chances of having a viable relationship. I feel embarrassed. What can I do to help resolve this issues? I know this sounds very petty.
