Tattoo?

Im a bit confused and dont know really what I want a tattoo or not having a tattoo.
I had the thought having one but Im not sure where and if I have it on my arm maybe it will get strched and loses details after a year or so. I dont know much about it. if it hurts to take a tattoo or is good or bad. I would like to know what you guys think and give me an idea of this primary though because my girl friend got 5 tattoos. I just got intressted abit. Would someone get bored from it to?
