Every gal is different ADD...and I have sensitive skin, so I understand if your wife's face gets irritated by a beard- from my experience "many kisses" sometimes rubs my delicate face raw, and there have been times where I can't go out in public for a while after a "many kisses" session because it obviously looks like my face has been rubbed raw (looks like windburn or a rash)
But I digress....I love Coffee Shop Guy's beard, I call it my loofah- it comes in handy in the shower and many places
So I chime in with the advise of mix it up! Shave it now...grow it again when the mood strikes you. We ladies like variety, and so do you men outside of the WT (where it doesn't matter what standards of "dress and grooming" you adopt)
