In My Opinon

I think people use the term "Fetish" too widely. Sure there are things that turn people on, but does that make it a fetish? I don't think so.
It's absolutely normal to get turned on by a variety of sexual things. A lot of things turn me on, but I only have a vinyl fetish. More particularly, a shiny vinyl clothing fetish (but then again I have rarely seen it elsewhere, and yes it has to be shiny). You can slap vinyl clothing on just about anything and it will get me interested to say the least. It's irrational and the reaction is uncontrollable (though my behaviour is controlled).

You cannot have a woman fetish. That is normal. Short skirts are usually not a fetish, since for the most part, people are thinking of what is underneath the skirt, not the skirt itself. Hell, I think leather looks pretty and attractive, but attractivity does not make something a fetish.

Moral dilemma

So when your brother asks you what kind of spray paint to use on animals, because he is afraid of injuring them, is it wrong to tell him?
