>>5904481I'm pretty sure everyone can recognize stuff such as cock or fuck hole as sexual, therefore it's not a fetish. A fetish is supposed to be something that at first glance might not come across as sexual.
Long ago, fetishes were regular objects such as a hairbrush or a bracelet, that had magical abilities.
That's what fetishes are in modern times : objects or body parts or actions, usually not sexual that have to ability to arouse certain individuals. For example, diapers are usually not sexual in nature so when someone asks you to draw character X wearing used diapers, some artists might not realize that they're being asked to draw fetish art.
