When I was beardless, (obviously), I nearly always shaving every day. It was extremely rare for me to miss a day shaving.... until...
These days. Of course I've only been without a beard very little for the last 7 or 8 years. This last time I was clean shaven, (last June) I only went about 6 months before growing my beard again. BUT... these days, when clean shaven, I often went a day, or more, without shaving.
The first few days of not shaving are horrible, IMO. I didn't like not shaving for those days.... I just decided to be lazy and learned to live it.
