It's uncomfortable to go to the gyno in the first place. When you're a girl, there are always so many things you worry about. Cleaning herself down there, might help ease her worries a bit. And so what if she doesn't clean up for you. It means she's comfortable being around you and being herself.

Shaving that area is time-consuming and results in painful and itchy regrowth whatever the razor and however much shaving gel and aftercare you use. Waxing is just as painful. She probably shaved herself for the gyno because she was afraid of being judged, as our culture these days is obsessed with removing natural pubic hair, even though gynos have seen it all. It's just scary showing that to a stranger. Take it as a compliment that she's not afraid of being judged like that by you. :) Pubic hair is a symbol of maturity and can be very sexy. Each person should do with theirs what's most comfortable, be it nothing, trimming, removing some, or removing it entirely.
