You'd want to do it as often as you need to, depending on your hair color too. I shave mine every few days, or at least when I see my BF. I do it in the shower, it only takes a minute.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
