Kink VS Fetish
since you're always asking about my name NikkiFetish & that generally leads down this path...& realistically it doesn't make sense. I could or should actually change my name to NikkiKink. Yet again I'm quite a mix of vanilla & kinky depending on my mood.  ;) 
Fetish by definition:
1. 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 form of sexual desire in which gratification is linked to an abnormal degree to a particular object, item of clothing, part of the body, etc.

Kink VS Fetish... Kink is something sexual an individual likes to do with themselves or someone else can totally be involved. Typically a kink is considered outside of mainstream/vanilla activities. Of course what's considered kinky is subjective. 

Some common fetishes include impact play (spanking), role playing, foot fetish, anal play, lingerie, group sex, sensation play, orgasm control, bondage, voyeurism, & many more.
