I rather enjoy the term vulva. The vulva-vagina spelling similarity of v_ _ _ _a is amusing, but I really enjoy the difference between the sounds and the meanings of those two words. Caressing a vulva, being inside a vagina, so delightful and different in their own way.
My two daughters, both not yet in puberty, have moved from “girl parts” to “privates” to “vulva”. I don’t remember the tipping point, but there were times when a mild rash, hygiene issues, or basic self exploration brought up the need for us to talk about specifics of anatomy. I am comfortable using the proper terms, and believe using the right words is one of the many small empowering steps I can give my daughters on their journey to being strong, independent, and confident women.
Knowing the difference between those two words and refusing to use them correctly make as much sense to me as referring to kidneys as nostrils, or ear drums as milk ducts. What is your problem? It’s fine with me if you want to age play the part of a little and use the childish terms of girly-bits or hoo-hah. As an adult you are free to use pussy, or whisker-biscuit, or coochie-snatcher. But if you are going to start using terms like esophagus, urethra, or cervix, you either use them correctly or you broadcast to others that you don’t know what you are talking about, or you don’t care about being seen as ignorant. Do you know the difference between cock and balls? How about breast and nipple? This is a medfet-kink-erotic web site. Words are the tools of our craft.
