I believe people are more inclined to think "Hey I want to get a tattoo but I need to figure out what want first" than "Hey that's a cool piece of art! I should get that tattooed"
In other words, I don't think it's weird at all. In fact, I think that's how most people end up with their tattoos. That's how I ended up with mine. I knew I wanted some, but I didn't know what, or where. When I figured it out, I did it.
