An overgrown lady garden is not a pretty site,
Well you wouldn't want folk to think you are a cave woman would you dear a little trim "down there" is all that is required to keep things nice and tidy!
Well sometimes its easier to keep it smelling fresh when there isn't any hair.
It's the current fashion, and many beauty salons not only wax legs, they wax down there too, rather than shaving. Some girls shave under their arms, some don't. Surprisingly, it might not only be girls who shave down there. I guess it's a way of feeling more feminine.
