I trim and maintain nose, ear and any other hair that grows in a manner that does not please my wife. I do not shave genitals and do not have a problem with excessive hair to begin with.
I have seen other bros @ EF say they shave their balls etc...To me this is rediculous, but to each his own...I mean once you shave it, it will grow back thicker than before...just like anything you can over do it.
