If you honestly are triggered, I don't suggest this game for you. This is a kink game and the sexual content isn't typically vanilla. It'd be irresponsible to rec this game to someone that'd have to be constantly wary of the content.

The thing I appreciate about this game is that most players don't use the warning section on the log posts for a pointless warning about potential triggers. If you know anything about triggers, you know they can be anything and are largely unexpected by most people. For instance, a description of a dark alley could be triggering to someone that was sexually assaulted in one. Anything could or could not be triggering. Many times it's something seemingly innocent that can set someone off. Basically, no one but you can know what it is triggering.

Instead of using such a blanket term that doesn't really mean anything, most players use meaningful warnings. For example, the usual log's info looks like this.

Who:
What:
When:
Where:
Warnings: Underage, bondage, violence.

So no, most people do not use trigger warnings. The entire concept of the game and nearly any thread could be triggering to someone. Instead, players warn for the particular events occurring and you can gauge for yourself whether it will be triggering for you.

You should realize for yourself that joining a game of this variety is just walking into a field of possible landmines.
