Aaron and I did something similar with balloons.

I wish I had a gif of Tulio with a sword…
Only one of these mooks is on actual drugs… XD
LOOOOOOOOOL
Hmm… What an interesting question!
I’ve honestly never thought of this before!
I’m just south of sloshed at the moment, so I wouldn’t read too much into my thoughts, BUT… I feel as if a lot of the “male” slang really is applicable to the female body as well. I mean, physiologically, it’s extremely similar: blood fills the corpus cavernosa (vesibular bulbs) and the clitoris, causing the structures to swell and become harder. I don’t think it’s far off to say that we become “hard” or “get boners”—although I personally feel silly saying “ladyboner” or “girlboner”, as if the female boner were some sort of strange variant on the male one. If I’m being really vulgar with my friends, I just say, “Wow, that just gave me a total boner,” without any sort of feminizing modification.
That said, most “slang” is going to be pretty raunchy and- well, not super respectful. Because it’s slang, and people can get pretty immature about sex. What I would keep a keen eye out for isn’t demeaning language so much as disempowering language.
For example- This is totally a personal thing, because I know a lot of women dig it, but I cannot stand the word “pussy.” The first male person I ever slept with started talking dirty to me, and (at the tender age of 17, bless me), I interrupted him to say, “Er… Sorry, I’m not too comfortable with that terminology being used on my body.”
His response?
“Oh! Sorry, do you prefer ‘kitten’?”
I was like… Seriously? Is this my vagina or is it a fluffy animal?
It wasn’t disrespectful, technically, but it definitely felt… robbing.
What I think I’m getting at here is that it’s all about how you see your own body, and what you can get behind. If “ladyboner” is your thing, then by all means, ladyboner away. If you like to say that you get “wet” for things, then say you get wet for things. If you like to think of your vagina as a delicate feline, then “pussy” is right up your alley.
What does seem to be lacking is exclusive language for women who like a more empowering angle to their slang, which I think is what you’re asking for. And honestly… While that sort of language does exist plentifully in isolated communities, it is pretty damn difficult to find in the mainstream. I think this is just one of those things where you have to Google hunt or use your own imagination, because what it comes down to is how you see yourself and how you want to be seen.
That said, to answer your question directly, in terms of whether I personally have any preferred slang… I dig “fuckish”, “horny”, “hard”, “clenching”, “boner”, “flush”, and “aching.” Mostly, I just say I’m “hard” for something.
Sorry if that answer was way more metaphysical than what you were looking for—but hey, there’s a million and one dirty dictionaries on the internet! :)
