I probably will do if I can't find any explicit guidance but it's hard to second-guess whether something would cross the line if I don't know where the line is. ;)

<Snipped quote by Vilageidiotx>

That seems really odd; one could write an incredibly graphic, sexually-explicit passage while avoiding commonly-used terminology* that would presumably get past Adsense, or quite a tame one by contrast using the 'wrong words'* that would get picked up.

* I'm reminded of the catchphrase of Leigh Francis (an unfunny character comedian); to "Smash somebody's back doors in", which, to my mind, is hugely explicit language bordering on the violent, despite using non-standard terminology.

You might be overthinking this.

"Smash somebody's back doors in" wouldn't get you in trouble.

While suggestive, it's not out-and-out graphic. It's not smut.
