you should only get a tattoo if its something you really want. i love my tattoo and i can't wait till i have time and money to get some more. i have my whole back done and loking forward to getting both my sleeves done over time.
if you have to ask yourself if you want one or why you want one, i don't think you should. should be something you want to get, know you want to get and won't have any regrets about it. tattoos are pretty permanent haha. good luck in your quest in getting one or not man.
and my tattoo artist is james tex -
