OP- you will be fine, you will more than likely feel no pain at all...if anything, I would call it an annoyance more than pain. Take 1 of those vibrating massagers with the little legs and hold it on the spot where you will be getting it done for a few minutes. To me that's what getting a tattoo feels like.
I must be pretty low class as well! Although I am prior military, and currently work for the federal government in a job where I wear business attire to work, hold a college degree, volunteer as team mom for various activities, attend church and live a pretty upstanding life. BTW I have a couple of tattoos- 1 on the outside of my ankle, 1 over my left shoulder, oh and 1 that is a work in progress...it covers my entire back.
Good luck and enjoy your new piece of artwork. Post a pic when it's done.
