Most psychiatrists and medical practitioners regard fetishism as normal variations of human sexuality. Inanimate objects, such as a red scarf, or a certain pair of boots may start a fascination brewing, that can lead to arousal. For some it may be a certain scenario, or situation that they play out in their head many times over until they are able to “act out” the fantasy.
For some, it can be a certain body part, a particular type of person, or the mere shape of something. There are different degrees of fetishism…mild to extreme. Common to extremely unusual or even a bit bizarre. Leather, latex, and rubber are common materials that may spark fetish-like thoughts.
In The Fabulous Fetish Boys, I write about a few fantasies, extreme fantasies, that may or may not be considered fetish worthy. These included adult baby, alien tentacle monster, bondage, and more. The story was written in a light hearted narrative, making it a fun read. You can read a free sample here: https://www.smashwords.com/books/view/277745
