It's something I've fancied doing but I knew girls that did & when the hair is growing back in I didn't like the look or feel of it! I have naturally dark hair so you can see the hair on my arms but it's something I've learned to accept so wouldn't shave them, arms is the only part of my body I don't shave!! ^_^
Sometimes mine need a small shave down the side of my arm where my skin is really pale as I have really dark hair...never my whole arm though
I remove hair from my arms and legs as I cycle. Also my tattoos look much better without the hair and a little baby oil.
Wife shaves her arms whenever she does her legs.
