Besides thorough and excellent hygiene, natural but trimmed is fine. If you're so inclined to shave, kudos to you. Removing hairs mid 'work' is a little annoying I must admit. It's almost like the episode of Curb Your Enthusiasm when Larry gets one stuck in his throat for a few days!

I shave around the base and the two boys. I leave the hair naturally above the base but the rest is clean shavin

Trimming makes your unit look BIGGER, also makes it better for oral, (No irritating stray hairs going in her mouth, down her throat.)  Statistically speaking, majority of women do not like the bald hairless look,  as it reminds them of a male baby.  Remember, You're a MAN, you're supposed to have some hair.  

a bit of ball licking and deep sucking, very trimmed to shaved is easiest.  If you have a mass of hair down there I will not be able to deep really deep or lick the balls without hair of some type getting in my mouth and gagging me.  Makes the oral a little less then seamless, and the break can take away from the experience.

Just my thoughts

Please boys! Pretty please groom yourselves down there!

There is nothing worse than getting a long pube stuck in the back of your throat.  It is just so annoying and seems like it takes the whole day to finally get rid of it.  Pure and utter torture.  Also, whileim all for shaving that area, it can rub a girl raw when the pubes are growing out from a shave.  It's like grinding my pussy on sandpaper and really hurts the whole day andthe whole following day.i suggest my personal method which is shaving all over but shaving with the grain,not against it, to prevent razor rash and then in the sensitive areas I just trim it to almost like a small little patch of peach fuzz.  Guys should do the same thing!  Just my .02 and hope my opinion helps in your endeavors on being the most considerate and manscaped gentleman ever!
