Howdy.
I got a tattoo not so long ago. About an inch square on my left shoulder. If I have any regrets it that I can't look at it to admire without a mirror or twisting at a near impossible angle. lol.
If I were to get another, it'd be somewhere astheticaly pleasing and a pleasure to the eye. My own particularly, and to others.
In other cultures, one would get a tattoo to describe their journeying. I got one of the kanji for drum. Personally pleasing to me, though no-one else knows the meaning, unless they ask.
If your unsure of where to get it, and what size, I'd suggest to henna a couple on various parts of your body, and since henna fades after a while, you could then decide where you'd want the tattoo on a permanent placement.
Or some other means.
Remember a tattoo is for life.
Rock on!
