I don't but I wouldn't mind one or two. The problem is I don't have anything really significant worth tatooing.
My father in law has a double headed eagle on his back (he is from Albania and it's on their flag) which is cool and, being from New Zealand, a lot of people have Maori and Pacific Island tatoos (being, as they are, Maori and Pacific Islanders). Those tatoos look particularly cool but, as that isn't my heritage, I feel it would be a bit try-hard getting some.
I occasionally come up with ideas I would like - but end up finding them lame weeks later so I'm happy I don't have any to date.
