My beard had a good couple of inches taken off it a few weeks ago, getting to a nice length again now ready for xmas party time.
I've had a few girls at work comment on the beard looking good, i think the wife likes it as long as I keep the neck/sides trimmed.
It's normally blokes when you're out going "Nice beard!" as they walk past. I walked into a pub once and i just heard "BBBEEEAAARRRDDD" shouted at the top of this guys voice, he looked like a massive fat viking and came straight over to our group. Started stroking my beard and saying how soft it was and what did I do etc. Never met him before and never seen him since.
Awkward eye contact though, that depends more on the whole person than the beard.
If it's a mans beard then you don't really do anything but if I spot some elasticated trouser bottom, shoe but no sock wearing nancy boy trying to be cool I just ignore them.
Anyone worried about itching. Wash it daily with womans shampoo, then use their conditioner, it'll keep it nice and soft while it grows. Although once it's established now I find that washing it keeps it soft for a few hours afterwards, but just leaving it and not using shampoo does a much better job of keeping it naturally soft.
Also, you'll have to learn to blow your nose properly after you've started growing one so you don't end up with a moustache full of snot!
