When the uninitiated speak of fetish, they see it only as a sexual thing.
I disagree.
Excitement is subjective. People crave the things they do for the same reason as they ride rollercoasters to scream; watch horror films to feel that wonderful flip of the innards at moments of tension; eat ice cream for the sensation of sweetness frozen to the tastebuds.
The thrill of one’s fetish should not be reduced to what makes one’s cock swell or pussy salivate.
It is more akin to a piece of music so beautiful that it causes the spine to shiver.
