Depends also on the Bull. My wife always kept it shaved smooth and she preferred that. But she changed it and grew out her bush when her Bull asked her to.
I fully agree. My wife used to keep it shaved for years until her current lover requested her to grow it out. Now she has a full bush for years. I have a lot of experience with either fully shaved or a full bush, and shaved is definitely so much better. But of course I do respect my wife's choice and her lover's preference for a full bush, even though I don't like it.
