Its a net positive though. You might look horrible but beards are magical.
I've had a beard for about 4 years now, and (while I was single) I found that not all girls like beards, with a good percentage of them disliking them.
However the girls who do like beards, really like beards.
It's been a huge positive for me, and obviously my girlfriend likes them (she's never seen me clean shaven)
