Lots of people obviously want one enough to pay good money. Is it possible to describe? Maybe you just want it because you want it? Maybe you feel good for a long time afterwards? Maybe it's often a really deep personal thing you wouldn't discuss casually? Is the pain part of it?
I ask here as opposed to somewhere more general because people here have a keen interest in quantifying things.
My subsequent ones were in my travels, a replacement for souvenirs. I have tattoos from Antwerp, St. Louis, NYC and LA.
There is also a rush of adrenaline during the process and after that can be addicting.
If you have no interest, I highly recommend not getting one.
The long answer is that "looking cool" is a social signaling mechanism. I now attract friendly strangers who recognize the specific symbols on my skin.
For a fixed cost, I have forever increased the chance of meeting people with common interests and actually realizing that we have common interests.
The downside, of course, is that some friendly strangers (and employers) may avoid me because of my tattoos.
I think, so far, that it's been a net positive experience for me. I'll likely get more when I have more expendable time and income.
The other I got as part of a worldwide art project.
That would be a meaningful marker of place, time, and relationship to me.
I have known people who like to get tattoos because the experience of being tattooed does something for them in itself, but for me it was all about the art I wanted to wear. I didn't mind the pain, but it wasn't about that. There is some symbolic significance, which I mostly keep to myself, but mostly it's just that I like the way it looks.
2. I would have a hard time deciding what to get since it was permanent.
3. Negative reaction to the ink.
4. Negative criticism.
