Random, but I got my first tattoo on the inside of my forearm and my wife loves it because she can see it while I drive. I got it before I even met her, but it worked out in my favor lol.
Definitely pick a spot based on the tattoo you want. Mine fit best horizontally because it's clipped from a Calvin & Hobbes panel. Like others have mentioned, if you're shy about having one, consider something easily covered vs somewhere less painful.
What is up with that title
