Nowadays, these two terms are often used interchangeably, but traditionally, a sexualized kink is considered to be a term used to refer to a playful usage of sexual concepts which are overt, accentuated, and/or unambiguously expressive of sexuality. A sexualized fetish is traditionally considered an object or situation of interest that causes sexual arousal. There is sometimes an implied notion that a kink was something done for casual fun, while a fetish would indicate a form of requirement for sexual arousal.
