Well... from my own personal experience, I kind of wish I mapped out a sleeve for my arms to sort of run on a theme. Right now, my arm is a clusterfuck of 10+ years of random tattoos. If I could do it over again I would have picked a central theme and wrapped my arm which just looks nice.
I say that because you don't have anything. If you're just getting this one tattoo, great. Good spot, not that painful (to me anyway, everyone's different) But if you think you might want to do more, a half sleeve, full... I would rethink it unless you have a DNA type theme going or this is it for you.
I hope that makes sense. I mean, it's your body but if I had a tattoo regret it would be not to get sporadic tattoos. I'd get one big piece on my arm or at least the same theme.
