I write in third person limited most of the time, and while I tend to use the same words, I try to use what would fit for the character whose head I'm in. While I usually wouldn't use cunt or tits (because they're words I personally don't prefer), if the character I'm writing thinks of them that way, that's what I go for. But I feel like few (if any, I don't know) women think of other women's clits as pearls or vaginas as blossoming flowers.

Vagina, cunt, pussy, breasts, tits, wet, damp, moist, slit, lips...all words that are awesome. I like that there's not one go to. I like that pussy has a different feeling from vagina has a different feeling from count. I think that's part of the beauty of the different words.
