I've not got a full beard,more in-between stubble and full beard,so a few weeks growth usually before trimming down to stubble.
I can only say from my own experience and what I do,but I trim the tash hairs if they're maybe too close to my mouth,so she doesn't get a mouthful of hair if we're DFKing.
As for dining at the y,longer is probably better as not as rough as couple of day old stubble.(if she's wet you'll get juice in your beard) I approach carefully though and let her get use to it and let her then either pull my head in more or sit further down on my face
As for your question on Romanians,I've seen about 4 or 5,2 were very good,I just reviewed one last night,and the other no longer seems to work. The other 3 were bad,thinking with my wrong head and hoping it would be better.
You get good and bad British and Scottish,but you can generally see if profile have been copied and pasted from others as not a full grasp of english or understand what certain things mean,also simple one word answers if you text them.
