I trim everything. #1 guard on the upper body, and #3 on the legs. I’ll razor shave my upper body for special occasions, but I tend to get a lot of razor bumps (especially on my lower abs) so that is rare. I shaved my legs a few times, but it takes fucking forever, so I haven’t done it in a few years now.
Shaving does make a pretty big difference in your physical appearance, especially if you’re lean. Veins and striations get revealed, even if your skin is on the lighter side. I’ve also found it’s much easier to get a tan on your legs if they have very short or no hair.
I’ve always had weird, thick patches of hair on my back, and finally decided to get it waxed. Looks way better, and really not that painful at all. Someone mentioned the neck above, the girl that works on me said the back of the neck is by far the most painful area of the body to get waxed (people always assume balls, ass, etc…not so apparently)
My wife did this to me once too. Same reaction, and it pulled out from deep enough to cause blood to well up at most hair follicle sites - It looked like my neck had been stabbed with a bunch of tiny needles.
