Sorry, I misunderstood the question. Of course, for masturbation the shaved cock and balls are the best. On the one hand the naked genitals are most sensitive than hairy on the other hand your hand can take a longer section on the rod meanwhile stroking. And last but not least if you watch your jerking in mirror or take a video, your genitals look much netter. When the hot spunk is trickling down on your naked rod, the feeling is divine !

At least trimmed if not fully shaved.

Shaved here as well. It was a bit of an evolution (devolution?) to get to this point but love the way it looks and feels. I heard a tip that allowing no more than about 1/4? of growth is key to it being easy and fast to shave and have found this to be true!

It depends on the seasons for me. Spring and summer. I go to nude beaches and resorts so I like to trim up. I have a nice amount of body hair so the colder months I leave my body naturally hairy. When I was a teen into my 20s I did shave completely, I will never again do that. Hair is masculine. I embrace it.
