If it sound like an autopsy... it too clinical and not sexy, still some slang word are vulgar or sexist, I rather use a discription of what the body part does or how it reacts, in place of slang or anatomical terms, to me it's whatever makes the story flow and evokes the right sexy mood.
Angry Cursing is another story, it calls for different guide lines, it need to shock!
I positively hate the word cunt it is totally sexist,...I wont use it for any reason what- so- ever, not even as a curse...and pussy is silly I can't take it seriously. I'd rather use wet folds, or moist petals. For Female insults I'd rather use slut or horny bitch.
As for men I perfer Cock, shaft, manhood over dick, but will use dick in cursing, even though it could have two different meanings in that context.
For what it's worth my 2 cents
It would be nice it they would come up with more cleverily discriptive words for sexual functions!
Even thought it probably considered anatomical or clincal...I'm sort of like the word ejaculate, it has its own funky class.LOL
