I hate dirty talk.
I love sexy talk.
They are not the same in my world.
Sex is clean. It can be wet and messy, sure. But with all that, sex is attractive and pleasant. Naturally.
Dirty -- filthy -- is pretty much the opposite. Filth is aversive and disgusting. Naturally.
.
So talk about sex brings to mind pleasure. Talk about dirt/filth brings to mind disgust.
.
Please, do not mix them up when I'm around -- especially when I'm seeking pleasure with you.

There's another shade in this range: "naughty". That probably depends on how you were brought up, but for me naughtiness is not something to be sought, it is just some minor social unpleasantness applied to sexy behavior. I would like to avoid being made to think about naughtiness; it is not a way to turn me on.

Some examples to make this more concrete:
Some sexy words: fuck, cock, pussy, suck, cunt, tit, nipple, kiss, lick, stroke, wet, squeeze, slippery, slut, ...
Some dirty words: shit, piss, stink, pee, filthy, nasty, dirty, slimy, ...
Some horrible juxtapositions: "fuck the shit out of", "nasty slut", ...
.
Just my own reactions and opinions ... carry on ... .
