I limit swearing among people I don’t know very well of either gender. Among my friends, I haven’t noticed any difference in who is bothered by it.

I only limit swearing in professional environments; meetings to be honest.

Everywhere else gets the shit and hell and damn that I use in regular language. No slurs and no sexual words like Fuck. But that's just good manners.

Curse words are like salt and pepper for the language. They're not necessary, but often add just the right amount of extra spice.

Oh, that’s an interesting thought, good point. I agree on the idea that slurs and sex-based stuff should be avoided (crassness should be fun for everyone, not exclusionary). I hadn’t put fuck in that bucket really, but of course it does have some sexual definitions.
