Seriously, what do you gain by having a tattoo? You just permanently destroy your body . Though it's cool but as Arun said, it'll ruin something sooner or later.
The only thing it could ruin is getting a job. I have money, I'm never going to have to work (other then what I'll do in the service). Ohh, and bitches loves tats, not all of them, but the ones I want around me do. It come down to it like this, every bitch that I sleep with will either hate or admire it.
Ohh, and tattoos usually wont hurt you getting a job. Offensive tattoos will. How do I know this? I know a lot of people with sleeves & body work.
