Dude, I had reservations but took the dive and did my navel with a banana post. I love it, really glad I did it! Next, I'm planning on doing one/both of my nipples. That's about all I'll get done, though - above the waist, only what can be covered up for work. I've also found a tattoo artist I'll be visiting this fall, for some upper/lower back work!
Take the step to la vida loca!
