First things first, let’s go through a refresher in female anatomy. The vagina is the inner canal inside your body, whereas your vulva is the outer part of your intimate area. The vulva includes your clitoris and clitoral hood, as well as your vaginal lips, also known as inner and outer labia.
With this distinction in mind, let’s say it all together: you should never wash the internal passage, the vagina, but you can and should clean your vulva, the external part.
The vagina is entirely self-cleaning, because in order to birth a whole human being, you kinda have to prioritise the tasks at hand and automate some of them, right? The vulva, on the other hand, has the same kind of texture and sensitivity as the skin under your armpits, so it’s recommended that you give it a daily wash, either when you wash the rest of your body, or separately if you have a fancy Italian bidet.
