I have four...but mine are very unusual...very simple geometric line designs. They're meant to replicate typical eastern woodland native designs from the 18th century. Two I've copied from prints or paintings of native warriors. The one on my left thigh is my own design incorporating some Iroquoian symbolism (sky dome, tree of life, scroll designs) and the fourth is an infinity symbol on my chest...which mirrors a related tattoo that my wife has.
I'll echo the comments about not getting all psyched out, etc. It hurts, but isn't that bad. They started my first one, an armband, on the inside of my bicep...which I was told was the worst place. It wasn't bad. You might feel some pain as they get up near your shoulder bone, etc. Fleshy parts aren't bad. Muscle parts sometimes spasm. Boney parts sometimes hurt.
