Girls today need a boy to show a little stubble...it is the only thing manly about them.
I think women have always found a scruffy looking men attractive under certain circumstances (Saturday morning and you’re fixing her car, for example), but these guys who use a $50 trimmer to keep their faces in a perpetual state of stubbly-ness (I even see guys in suits and ties with briefcases walking around with the perpetual 5 o’clock shadow) are slavishly misapplying the principle.
