When I was a kid, I had the fantastic plan of eventually producing offspring with another Japanese person to spread around more full blooded Japanese people instead of all these mutts you see these days. Then I grew up and realised I was being a dumbass about it. Haven't thought about race as a factor in years, though I'm generally uninterested in black people in any romantic sense. And most of the other Asian nationalities. Guess I do consider it subconsciously. Best described as it depending on the race, I suppose.
