I have worked in the tattoo/piercing industry for over 10 years so I am speaking from experience. Get away from the tribal crap...honestly.
We see more people come back after a few years with nothing but regret about tribal...I personally have a HUGE tribal piece that covers my entire right shoulder , runs into my neck, goes around onto my back, down my ribs and across my chest...BIG mistake. I am fortunate enough to live near and be friends with one of the best tattoo artist in the state and he is actually covering it up...long, many layered process.
I wish I would have taken the time and actually thought about it and gotten something original...anyone (and nowdays everyone) can get a big tribal piece.
You must live with what is on your body or go through what I am now, which sux!
Let the next piece you get say something about your beliefs, what kind of person you are, what you feel in your heart or anything you are passionate about, and I guarantee you will be MUCH happier.
I have read your posts. You are a very unique person with a flair for life and all that you want from it...a tattoo chosen only because it looks cool at the moment will never be for you, and after people see it once or twice, the magic is gone.
Sorry...this is just my rant, and speaking from experience.
Coincidently, if you want to email me and tell me about some of the things you like, what inspires you or any ideas you have, I can have you something drawn up custom and scan and send it to you...you wont be dissapointed, J is an AWSOME artist!
Let me know...and good luck with whatever you decide.
ps. A navel/stomach tattoo is not feminine at all...ever see a 350 pound Somoan or Fiji warrior you would call feminine?? ...but that is a different story all together
