Could it be that bald pussy was led by the porn industry? If you check out 70's and 80's vintage porn it's all full on bush but more recently it is mostly fully shaved. I suspect this was because bald pussy was "better" for viewing in close up shots etc.
Anyway, back in the 80's I caught a dose of crabs from a bushed civvy and ever since then my preference has been for shaved as my subconscious tells me that bald is "clean", as it were. Ridiculous, I know, but that's no doubt why my preference is for fully shaved.
