Been shaving shaft, nutsack, taint, anus and ass crack with a maintenance trim on the bush for close to 20-years now. I'd say it's a clean look, not pubescent looking at all because my pubes are near natural, with the exception of a little trim and shaping around the sides. My thighs are lite haired, so I don't go there much. Anytime I shave the thigh area it breaks out bad, so I'm leaving it be and as I said, not much hair there anyway. (If anyone has a cure for shave break outs please let me know, I've tried a lot with no success to stop my thighs from errupting after contact with a blade or close trimmer).
The benefits, in addition to looking clean, I notice no hesitance on the part of tongues to eagerly lap around my balls, taint and anus enhancing oral pleasures. And, I find my balls go into hang mode more often after shaving for whatever reason. Before I shaved, or if I get lazy and let it grow in, my nuts stay tightened up and I, for one, like the feel of my nuts hanging and slapping during sex, of course until they rise to the occasion of expelling a load.
The only downside to shaving is the ever present nubs which start blooming within 24-hours and the occasional ingrown.
All that being said, I think the blessed are men with light sparse hair on their balls and a little tuft of hair just on the underside of their nut sack, hairless taint and ass all topped of with a nice plump of pubes on top with little to no thigh hair. I've always envied that natural clean look, which is handsomely masculine.
