Smooth can be nice (tried it in the past), although I definitely prefer it fully furry. It just really pleases all my senses. It looks great and manly, it feels so nice to the touch, to brush a finger lightly across some nice ball hairs, the associated musk is a very great thing, and so forth.
I very much agree with you
Puberty:
As much hair as possible. That meant a few hairs but me and my buddies were proud to have some hair on our balls. :-D
Then:
Shaved or trimmed:
Now:
No shaving and occasional trimming (like once or twice a year).
I grew to love having by balls hairy. It is so much more practical. And better to touch them - even my wife likes it much more. Contrary to my expectations, my wife hates shaved balls and loves them hairy and even sucks them frequently.
I prefer mine smooth, started shaving my scrotum 30 years ago and the amount of hair removal increased quickly to all of my penis. Then in time trimmed above, it got shorter, eventually all off. My late wife preferred smooth and so does my partner now, I think most women do from other experiences and observations.
I rather like not being furry. My dad was a furry guy, he had a sweater on his whole adult life. He wasnt much of a house cleaner so when Ive helped him move a few times I almost got sick each time. The amount of body hair under his bed, around his room gave me the chills. My son is the same way, thankfully Im not as bad.
I started trimming about 25 years ago then moved to shaving first the public area, I liked the feel and look then I expanded to my upper legs then chest and belly. Now Im head to knees shaved but keep my arms and lower legs trimmed. Been a smoothie for 20 years.
