The hairless body is way best in every way. But there is a right time, so to speak. When your young and don't have that much hair, why bother, even though a hairless young dude is so sweet. As we get older and more hair patches come about out bodies and start to grey, then its times. If we have fine light hair, shaving is ok for most. If, like myself ones hair is quite coarse, then a very close 5 o'clock shadow trim is best. No bumps, nicks, red spots or rash this way. A close pubic trim and then a ballsack tweezing is best. It does take time to learn all of this but its worth the effort. May I say a Sunbeam beard trimmer is my fave. Why I even take it to the beach sometimes and trim up there.
I must say, I have learned to leave my clean little anus and perenium hairy, dark and mysterious. When on all fours adjusting my towel and such, with legs slightly apart and back arched downward, the lovely black hair is visible and very nice.
So, I say, hairless is so nice and convenient. While using lotions, toys and just plain old massaging in ones own milk, the slip and slide is wonderfully clean and delicious on a hairless cock.
