Maybe no it wouldn't. There are more definitions for "turn on" than sexual.
From Miriam-Webster: turn on
1: to activate or cause to flow, operate, or function by or as if by turning a control <turn the water on full> <turn on the power>
2
a: to cause to undergo an intense often visionary experience by taking a drug; broadly : to cause to get high
b: to move pleasurably <rock music turns her on>; also : to excite sexually
c: to cause to gain knowledge or appreciation of something specified

Even the word "fetish" can mean other than sexual.
From Miriam-Webster: fetish
1 a: an object (as a small stone carving of an animal) believed to have magical power to protect or aid its owner; broadly : a material object regarded with superstitious or extravagant trust or reverence
b: an object of irrational reverence or obsessive devotion : prepossession
c: an object or bodily part whose real or fantasied presence is psychologically necessary for sexual gratification and that is an object of fixation to the extent that it may interfere with complete sexual expression
2: a rite or cult of fetish worshipers
3: fixation
