Doesn't matter to me either way. Regardless, shaving that area of the body tends to result in razor burn... Not exactly the healthiest thing one can do, as it can irritate your pores, possibly even leading to infection.
I wax the outer sides & shave the lips and keep a top area timed down to a nice little shape so I don't look like a bald eagle
I don't get razor burns. need to use a nice razor ( not cheap )
for the guys trim or shaved is nice , balls are fun to get into
