My opinion is heavily biased because I think facial hair on a guy is so sexy, so LEAVE THAT GLORIOUS BEARD ALONE! lol jk. But if that's you in the pic, that's a mighty fine beard you got there sir ;) Or maybe you can shave and leave some scruff. I like a little stubble. I was never into the "baby face" or "clean shaven" look. My opinion is biased cuz I love a nice beard, so I'd say leave it. But do as you please, even if you shave it completely, it can grow back. :)
What do you like? I've a beard before during the 2011-2012 Hockey season lol. It itched like hell. When it came time to shave it off too forever. I say keep it if you like it but shave it if your sick of it.
Trim the beard whenever it gets messy, but never remove it completely.
