I have one on my upper arm. I designed it, and the tattoo artist faithfully traced it onto my skin and colored it in. No one sees it unless I wear a sleeveless shirt (so... just at the gym) or if I take my shirt off.
I thought about my tattoo for over two years before I got it; had to make sure I actually wanted it and that it was not a phase, or responding to a current fad.
I’m very happy with it and it’s a very, very personal symbol for me. My spouse doesn’t mind it, but rolls their eyes when I talk about getting another on the back of my calf. Been thinking about that one for 10 years, so I’m not too attached to it as a concept and it will probably never happen.
These days I’m more interested in dyeing my beard, anyway. I look amazing in blue and get a ton of compliments every day.
