You should only get a tattoo because you want it and have thought carefully about it, not because everyone else has them, just remember that if you change your mind after you have your tattoo, its not that easy to get rid of and very expensive, just bear all this in mind, think it through, what are you actual reasons for wanting this tattoo, if it is purely for you then go ahead, if you are that worried about what everyone will think then you may not be ready for this tattoo.
