where you get your tattoo is completely up to you..it is a very personal item that will be with you for life. However, with that said perhaps you have seen tattoos that you think look good, and think to yourself I'd like one there.
I got my first tattoo when I turned 40, and it was a small Kanji character meaning Zen, and I got it where the adonis belt cuts down towards the pubic area (a private tattoo).
The second one I got a few months ago, and it is on the inside of my wrist on my left hand and it is animorphic calligraphy, Arabic meaning love & peace. I had seen a movie where one of the guys had a tattoo on his wrist, and thought...I like that.
Now, I have just submitted the inkwork so to speak to my artist for a full back tattoo in a south Pacific motif that has several symbols and meaning to my life...it will spread between my shoulder blades then continue down my spine and end at the top of my butt cheeks...actually sort of go between them.
So...getting inked is a very personal thing...make sure that you have an idea of what you want...there are a ton of resources on the net. I chose things that were less common for my last tattoo, and the one I am planning...as I don't want the typical tribal armband that was way over done...and continues to be.
Be original, and make sure you like what you are getting...make sure it moves you, and says something about who you are as an individual...because it will be with you for the rest of your life.
I hope this helps you.
