Try to imagine what it would look like 20 years or more from now. Depending on where one gets it done and how their skin ages overtime they may come to regret it. There is a huge market these days for companies that either "fix" tattoos or remove them.
Lastly depending on what your occupation is you may want to have it located in a spot that would not be exposed during interviews or in the workplace. Not all hiring managers are fans of tattoos. They want their employees to represent the company with a clean cut image.
Some people are also reluctant to date people with tattoos.
Beauty is in the eye of the beholder.
