Shaving or trimming is kind of personal preference or maybe the preference of a mate. I've moved from trimmed up top/shaved below to shaved everywhere down there. Looks better on me and she likes it. Being shaved is also the most common thing for men and women at the swinger/nudist places we go to, although trimmed up top isn't uncommon. My experience is that women prefer shaved balls and if you're trimmed up top, just don't have it prickly short or look goofy like a landing strip, or something. Or if you have a really hairy torso, don't shave and leave some patch like a stark bald spot on your groin, trim instead. I've also learned that hardly any women like back hair.
My shaving kit is a regular quad blade face razor and an electric beard trimmer. I shave in the shower with just body soap or shampoo for the shave cream. I use the beard trimmer to keep the chest/stomach hair from looking like a forest. I used to use the trimmer when I trimmed above my unit or to get it short enough to shave. I do that in the shower, too, fast and easy. After I shave, I use a cotton ball to put on this stuff called "No Bump" that my gf gave me - works miracles to avoid bumps or ingrown hairs.
