My attitude towards language, it turns out, is much the same as that of Stephen Fry. With a few exceptions, I don't think there is such a thing as a bad word. If you liken words to colors, then the broader your vocabulary, the greater your ability to express yourself in any given situation.
Although I have dropped the occasional verbal clanger in unappreciative company, by and large, I'm fairly adept at communicating with others in a manner to which they are accustomed. I don't enjoy offending others (unless they thoroughly deserve it!) and take care not to swear if it will upset those around me. Most of the time, I don't feel like using salty verbage but, by golly, them sure are fun words to have around on the offchance you'll need 'em
For some reason, the F word said with a soft Irish brogue just sounds wonderful to my ear. I don't know how they do it. The fact that the Irish usually substitute an "e" for the usual "u" softens it's impact too, and lends it some character. The British have a lot of quite creative ways of being crude that can add much welcome humor to the proceedings.
On other occasions though, cursing can come across as crushingly banal. I think it has a lot to do with the vocabulary, intelligence, and general communicative abilities of the speaker. If someone swears a lot, and I get the strong sense they are doing it because they can't think of any other words, that's not too appealing. If, on the other hand, the speaker has a fast wit and a broad vocabulary, it is a great deal more palatable.
