I use an electric hair trimmer set to the long setting (w/o attachements). I use it to reduce the length of my body hair, not "shave". I think it helps. helps to use a mirror & good lighting (& caution around "the boys"). yes, you can trim the boys as well, but again w/ slow caution. throw down a towel so you can shake it out, outside when done, then launder it to rid of the rest of the hair. if the towel is not big enough you may have to vacuum a little afterwards. I like the big wide ones, not the narrow units meant for facial hair

this may be the one I have

Wahl Deluxe ChromePro 25-pc. Haircut Kit

other family members use it as well. if they drop it & the head goes out of alignment, I recycle it & get a new one

the only other thing I use from the "kit" are the scissors. Wifey likes the long hair clips, not sure why or when, maybe when doing her makeup?

if you've never done any man-scaping, then the 1st time may be a shocker. but the next cpl times you'll have less to trim

Wifey does my back once a year sometimes less often. when were were separated for 4 months I needed some help so found a female hair-cutter near my bachelor pad who obliged me. when she was done w/ my back she offered more but I told her I was all set. fwiw: she told me how she prefers men who are shaved (no hair anywhere) & that her husband doesn't do any man-scaping
