1) The Hair on my face and Chest is very splotchy so I can't let it grow out without it looking bad.
2) Have you ever tried doing any oral?
3) Hair is a notorious place for having bacteria grows. Bacteria are not a good thing to be getting into a wound from my "Play Piercing" sessions. I'm also into having piercings done, and doing other mods where I don't want to have get infected.
Spending time shaving or finding other methods of hair removal eats away at the time I have to play.
