Is it just me or it seems that @Godstud always has a picture of sexy women just setting there waiting to be posted when the time calls for it ?!
For the topic, as others have pointed out, it depends on why you don't find anyone outside your own race sexually attractive.
If you hold other races to be inferior and thus can not be attractive to a point where you essentially brainwash yourself into never finding them attractive, then its racism.
If its based on certain physical features that a certain racial group simply does not attract you sexually, then no its not racism.
For example I personally am very "picky" in regards to whom I find sexually appealing.
For example, I find actress Amber West to be beautiful and appealing, but I don't find her fully sexually appealing because I consider it a huge turn off if a woman's genitals (i.e pussy) have a very dark shade to them which she most probably have. So basically sexy in general, just not all of her.
Does this make me racist ? I don't believe so, because its not racism to have specific sexual preferences in some or other areas. Its just normal.
And in general, most people, will develop their sexual preferences based on their surroundings during their up bringing; As such it is very natural to develop a preference for specific type of features that just happens to be the most common among the group you belong to.

Dude, studies have shown that guys don't give a flying fuck about a chick's skin or even appearance. Guys are less selective than girls are.
One word; Fetishes.
