It's a very slippery slope with grooming anyone's doggy though ... If it is something brand new for a gentleman poor doggy might be confined to the doghouse after.  

As for down south...A nice trim is always a good idea.  
And I have offered assistance to those gentlemen who may not be experienced in that area. Or for those that may have difficulty reaching.  

I have personally experienced EV's grooming services, and they are second to none! It's incredibly erotic and a huge turn-on to have such a gorgeous, sexy woman take care of one's grooming. Then she takes your shiny new C+B for a spin. Sublime!

I have seen couple of ladies who were natural down below.    While I avoided dining,  my JR felt it ticklish being in the middle of the bush especially in mish.

As long as the beard is soft and trimmed, it's awesome. They do make oils to soften beards up over time.
I do like a nice shaved face too. If it's rough it hurts on both of my lips

Extra traction

But it has to be a beard.... Not a 5 o'clock shadow lol.

I like both facial hair and clean shaven just as long as it's not really rough stubble because that can hurt sometimes.
