Muck,
Make damn sure you really want a tattoo. Talk it over with your wife, because if it's private, then she will only see it. Remember too, if ya hate it later, regardless of how good the laser specialist is, they can not make it look like normal skin, especially with some of the deeper colors. I made a mistake at 20, and I thought about it for a year before I did it. Now I am 30 and am in the process of going in again to another skin specialist to see if they can graft something there that may look less like a big scar.
