I do not have any tattoos. I seriously considered it years ago, back when nobody had tattoos except circus people, ex-cons and sailors. I would have put it on my shoulder and it probably would have been the Grateful Dead icon known as "The Contemplative Jester."
However now that tattooing has become so mainstream, I've lost interest in it. I have the heart of a hipster that way, it spoils things for me if something gets too popular. It's sometimes justified. For example back in the 70's when you could get Grateful Dead tickets right up to the day of the show, we used to say, "More people should be into the Grateful Dead!" Then our wish came true and the Dead in their final years were the highest grossing touring band in the country. It also become hard to get tickets to shows that sold out within hours of when they went on sale. So be careful what you wish for.
Anyway, here are some of my friend's tattoos:
Belly button lizards.
This is the one I like best.
