As the founder and past owner of the first licensed tattoo shop in Texas, Crimson Dragon,
www.crimsondragontattoo.com, I have tattooed thousands of folks. People have many reasons for getting tattooed and what is valid for a given person may not be to your liking, but you must accept its validity for that individual, nonetheless. Getting a tattoo puts you into a group of people in our society who get into body modification, and not all who choose to do so are necessarily trying to be different. As one poster said, some folks with a good deal of body coverage do tend to look alike, but that is fine with them: They are members of a tattoo tribe, of sorts. They know that each tattoo they have has a story behind it, a special significance for them. Some do get tattoos for no specific reason: They're just in the mood to get some ink. Interestingly, former junkies have told me that they like the sensation of the needle and some actually report, at times, being able to taste the ink. Other folks say that the needle sensation centers them, calms them down. My seventy plus hours of going under the needle has always allowed me to focus my thoughts and obtain a special clarity.
If the original poster is ever down in Austin: Send me a pm and maybe we can put something together for you.
