Why the F*** Not?

Your Fiorella is a born rebel, especially against herself.  All it takes is her making a declaration like "I will never ever use slang or medical terminology for sex organs in my books" to challenge herself to do the same.  Thus while genteel Laurel Harlow, the heroine of Kinkaid House, couldn't even bring herself to say "damn," much less refer to her lover's private parts, Lolly Redlander, the free-wheeling heroine of Princess Redlander (which will probably end up retitled) uses all the words and then some.

Now, the question is whether Fiorella has Lolly using a blue vocabulary because it is in her  character, or whether Fiorella set up the character to use that vocabulary and thus prove herself wrong.
