Turn-On Tropes

]

"1. If it exists, it is someone's fetish.\\"

2. If it has even crossed your mind, someone out there has a fetish for it. "-- An Internet rule sometimes known as Rule 36."

An index of tropes that are commonly regarded as Fetish Fuel. Now these are objective tropes. They just also happen to be turn-ons for a lot of people.

If writers are really concerned about avoiding indecency in works for kids, this is a good place to start. This is the real Harmful to Minors stuff. Not that sissy swearing and violence.

Conversely, it's also a great way to "sex up" a work without being explicit. Use this for good or for evil. The choice is yours.

Oddly enough, these tropes are rarely mentioned as a Fetish in fiction, at least mainstream fiction.

And when these tropes are deliberate turn-ons, they rely on Rule of Sexy.
