Is it racist for me to usually only be attracted to one race?

By the definition of racist he is technically correct I guess. Racist is defined as a person that believes one race is superior to other races. Hate is not required. If you believe that one race is more attractive than all the other races, that is a type of superiority. But in practice, most people associate a racist as a person who has hate toward another race, and for that reason I don't personally consider you a racist.

I will say though that most people who prefer blondes to brunettes will have the occasional brunette catch their eye. So if you have have never been attracted to even one person of a particular race, I would find that a little odd. I know that is not what you said, so not saying that is the case, just saying.
