I grew my first beard in the school summer holidays when I was sixteen, and repeated the process annually until I left school. I have had one ever since, apart from four brief intervals: two for plays I was in, and two when my electric beard trimmer went berserk and I had to restart from scratch. It was once jet black, now it's white, and has always been kept trimmed, shorter now than fifty-odd years ago.
As for beard hair being pubic - of course it is, in the sense that it begins to grow with the onset of puberty, and tends to be equally wiry. Anyway, what's wrong with pubic hair?
Thank you grumppa for providing us with observations from our male colleagues!
(At least, I'm deducing you're a chap? If not, mega-apols?)
Any other menfolk around to give us their views, in the interests of balance?
