Oooh, I've always wanted a tattoo, but I too am afraid of needles! My biggest concern is that one day I'll get up the nerve to do it, and then right in the middle of having it done I'll find it too painful to continue, and there I'll be...a smudge of ink/halfway way done tat, and that I'll have to live with for the rest of my life!
That's exactly what happened to my brother-in-law! He has a little ... um... squiggle thingy... about 2" long on his back.
