Proclivity (noun) : A natural propensity or inclination; predisposition; a strong, inborn preference or fondness for something:
"Inclination" implies a mild interest in something. "Proclivity" indicates a strong interest or fondness.
"Fetish" implies an unusually strong, even unnatural proclivity toward an object. The word "fetish" is both mis- and overused, so bring "proclivity" into play when speaking of strong but comprehensible preferences. "He has a proclivity for peanut butter and guacamole sandwiches" or "She has a proclivity to overstate the historical importance of her ancestors."
Predilection: A partiality or disposition in favor of something; a preference.
