Another way to think about it - if someone near and dear to you or someone you respected read your manuscript - would you be embarrassed they found out you used the F bomb?
No, not even remotely. I am not a person who is bothered in the least by profanity, and those who are near and dear to me know this about me. I freely drop the F-bomb when it's warranted around my mom and grandma (my grandma, by the way, uses it more than I do. I think that's where I got it from.) But you do bring up a good point, for those writers who are sensitive to such things.
The bottom line, I believe, is that we each have to make our own decisions about it's use depending on the story we're writing, the appropriateness of use, and our personal situations. I use the F bomb in contemporary novels - but I won't get anywhere close to it in an historical. Puma
My only problem with my particular F-bomb situation is that I can't think of a better way for my antagonist to accuse my MC of adultery. It's in the heat of a very intense fight, and the accusation sets off my MC's decision to do something very drastic, which changes the course of all my characters' lives. I wanted the instant of accusation to be shocking and foul, but not jarring to the point of ripping the reader out of the setting.
I haven't yet come up with a better way to word it. "Sleeping with" doesn't have the offensive shock of "fucking," and its syllables are all too soft and airy-fairy for an enraged scream. If the Egyptians had a great word for the boinkety-boink that would do the job, I haven't found it in my two years of research.
I'm having a hard time here, wondering whether I should keep it or cut it. This might be one of those calls I have to let a professional editor make. I just don't know.
