'Cum' also makes me cringe whenever I see it in a fic because it's so juvenile; I also dislike use of the word 'cunt' except when it's used in dialogue. I like keeping the descriptive parts a little more vague/metaphorical so that when a character uses dirty talk it has more impact, but I've read some great stuff where the writer was explicit throughout.

I'm also frustrated that words that refer to female body parts are considered so insulting versus the male ones. 'Pussy' is such a cute word; it really shouldn't be relegated to an insult. I am also rather fond of the word 'cock' as well.

I'm having a hard time finding a short euphemism for 'clit' that I like. I've played too many online games so 'nub' makes me think of idiot 12-year-old boys, and 'pearl' is a little flowery. 'Hypersenstive bundle of nerves' gets a little old after awhile. ;)

Also, the first thing that came to mind when I read that hilariously bad 'ruff' quote was McGruff the Crime Dog.
