Words are just that words and if your consenting adults and it works for you then use what the heck you like.
I never swear in normal conversation but in bed the devil himself would blush.
I think if your in a good relationship you can call each other anything once and then after just say thats lovely but don't call me a whore etc it does nothing for me and infact turns me off.
In those circumstances people will find out very quickly what the other likes and does not like and that way you can get on with your filthy mouths in comfort that your not going to offend each other.
Personally I find that it's a shame women get all the dirty words, I'd love my wife to have something similar along the lines of slut or whore to call me but when she uses those I find it hard not to giggle a little. I guess bastard is probably as dirty as it gets for men like me.
Mind you I'm a dirty perve and my wife is very open mided so wer probably have less issues with llanguage. Now if I actually called her a slut out side of sex that would be a different matter and would cause no end of upset.
Nah daddy would put me in the same frame of mind as imagining I'm fucking margret thatcher, but heey like I said if she said it , I'd just give a little no thanks hun, just call me love.
While reading through this thread I randomly thought about one of my semantic like / dislikes. I really think it is bad to say "can I get" or worse. I always ask "may I have" I know it is old fashioned but it is more polite and no worse for that.
Like so many others have said, it depends entirely on the mood and setting. If we're making love (yes I know we're married, but we still do it sometimes) then all I want whispering in my ear are sweet nothings. If we're doing the nasty because we're hornier than a toad in mating season then no amount of dirty talk could make me blush. Sometimes I like acting slutty, so being told I am one is a natural extension.
As for doing it in public, if it's doing dicreetly, somewhere in public but just out of earshot of everyone else, then it's definately going to get the juices flowing enough to want to put it in practice when we get home - if we get that far.. x
