How come other ethnicities flirt with me but not my own?

I live in a multi-ethnic city and I've noticed that the women who are Intrested in me sexually or just dating are mostly east Asian, white and black. I'm middle-eastern and other middle eastern girls don't seem to see me as a romantic partner. I don't have much problem getting other girls but I really want to marry and live with a girl from my own country and culture. why is this?
