"I thought, 'What would be the worst thing to have on your dress?'"
In a world where women continue to allow themselves to be taken in by bullshit ageist messaging, a single gray pube doesn't necessarily worry me from a desirability standpoint, although it bums me out. For me, a gray pube means time is passing, and it's not the pube I'm afraid of.
I'm of an age when most people came into adulthood with as much hair (pubic and otherwise) as they could muster. Therefore I can attest to the hairless trend not being in fashion during the 60s and 70s. By the 90s, though, the hair-free look was popular.
If you're going to shave down there, watch this first.
