I should have been shaving twice a day since I was 14, and can grow a pretty luscious beard in 2 weeks. I went years shaving intermittently (once a week was probably average), and so I looked like The Homeless George Michael. As a result of my laziness, I was sent home from high school to shave twice.
When I was first allowed to grow a beard, I varied between THGM, weird mutton chops, a van dyke, and then a couple of years with a goatee. I eventually shaved that off for a job search, and displayed my little “butt chin” to the world for awhile. After I got married, I reverted to switching between THGM and more van dykes and moustaches for years, but my wife always complained (“It doesn’t provide the right suction!”, and “Cactuses are pretty, but you don’t want to kiss them.”).
Then, I fell and split my chin open. I couldn’t shave, because I’d shave out the stitches. After they came out, I couldn’t shave for another two weeks because the doc was worried I’d slice open the wound. Full beard was a forgone conclusion, because I wasn’t going to shave if it contradicted medical advice. 
Oddly enough, my wife did a wonderful painting of me in that beard. If I may be so vain, maybe the best work of her career to date. However, when she ended up being exposed to it day in and day out without an artistic or medical reason for it, the old complaints arose.
Nonetheless, I still loved my hirsute face, and toyed with several silly styles. I had “The Rent Is Too Damn High” for awhile (“It’s like kissing a wet dog”), and I remember chasing my wife around the house, trying to kiss her while I had a Hitler toothbrush (“Noooooo, why are you doing this to meeeee!”)
Like all mostly sane people, I came to my senses. I thought about what beard I had when we started dating - it was just a goatee! She even used to chew on it! (Odd, but endearing) I grew a goatee (now salt+pepper instead of brindle), and started shaving the rest twice a week. There was much rejoicing, and no complaints. On my dearest’s request for a little more sexiness, I grew the sideburns out. I trim the sideburns, and let the goatee grow ( not quite ZZ Top length, about 7 3/4" after about a year and a half ) . We couldn’t be happier - I have something to fondle besides my privates when thinking, and proper suction is achieved if we’re within a day or two of the twice-ish weekly shave.
The only drawback now is that the kitten has decided the beard is a great toy, while I’m asleep. Wow oh wow, that was long and detailed. In my defense, you asked about my beard.
