I don't shave my beard, haven't for 2 years now, I just trim it. As for the rest, it depends, really. Usually I grow it out for a week, which is a considerable amount but at that point it gets annoying. If I'm staying at my girlfriend's [she lives in another town], she doesn't like it when my face is rough, so I usually shave every day or two [she usually lets me get away with it].
I usually shave every day, but sometimes I get lazy and let my shitty beard grow to highs school freshmen-like lengths.
I have to shave every day. By the end of the day I've got noticeable stubble. By the third day I've got a noticeable beard. After a week I'd probably look like a bear.
Yeah. Usually I'd shave on Sunday or Monday and let my facial hair grow for the rest of the week before I'd shave it again the next Sunday or Monday. But it got to the point where my face would get really itchy (I've got psoriasis), so I'd shave just so my face wouldn't itch. By doing that it set all kinds of wheels in motion and my hair was growing faster every time I shaved -- so now I'm down to shaving every day. I shaved Thursday morning and haven't since. We're going to see how long it gets by the end of the month.
Every second day, or at least I should. I usually leave it like a week, then I start getting in shit at school...
I shave every other day. Hair doesn't grow back too fast on me. But I need to be clean shaven. It freaks me out to have hair in places other than my head or arms.
