yeah its about personal pain tolerances, soft skin, or skin that has a lot of nerves under is is the worst, i.e. underside of your arm! im a glutten for punishment and im thinking about getting one under my other arm now, its easy to hide them that way! shoulder blade shouldnt be to bad for pain, and i have been told by a few tattoo artists that females deal with the shock of tattooing better, something to d o with child birth, their bodies accept the pain??? Any doctors here can back that up? lol
