I'm up to one week's growth now.
Dolphin, who said men don't have to shave? Some days, I have to shave my face twice. I've had to shave my legs and chest more than once for work (and a couple of times for Ptown); trimmed my forearm hair; and of course, I shaved and trim down there.
Stop worrying about what I'm doing -- focus instead on what you're eating.
