A sexual fetish would result in you becoming sexually excited by the attributes you mention. You did not indicate that, so it is likely that you have only an aesthetic or cultural preference, rather than a fetish.
A fetish is a specific association between some object or practice and stimulation of the sexual centers of your body. It is one of the "paraphilias" (patterns of sexual behavior that require the involvement of things other than straightforward physical and emotional stimulation between two adult partners). You can look these up on the web. The description of "fetishistic paraphilia" does not equate to your description of your preference.
(Just so you're prepared, some people say there are over 500 different fetishes, but mainstream psychiatry sticks with eight, plus one catch-all category. And "digs Latinas" is not one of the 500+, btw.)
