Pussies were there right between her legs - at least, they used to be. Sharp, thick, smelly and hairy. To be hidden and to be sought out and fingered. Clearly the object of desire.
Now they seem to have disappeared. The wonderful space is there still, but the texture has been elided, as if the build-up is no longer important. The details ignored for the final punchline.
There's a fetish to self-groom - but the allure has been erased.
