Minidancer:
I do think they are addictive though.
I agree. I have one, on my forearm, which I got to support my wife. She wanted to get a tattoo to cover a large surgical scar she had on her leg. She was afraid of the pain, so I agreed to get one at the same time, so we could share the experience (and, I guess, complain to one another if it hurt). Turned out mine didn't hurt very much at all, just a little stinging especially when they filled in the colored parts, but her's hurt more. That was about a year ago. I have wanted to get another one for the last 6 months, so I went today to look. I picked one - an armband tat cuffed on the bicep of my other arm, to sort of balance the ink out - and I am getting it done on Wednesday.
No one who knows me - especially those who have known me for a long time, like my family - would ever think I would get one tattoo, let alone two. I just don't seem like the tattoo type, if there is a type. But here I am, with two of them (as of Wednesday).
I think I will stop at two. Though, you never know.
