Tattoo's always seem to cause a debate. Recently, my business tutor announced on Facebook that he was going to get a tattoo, and the outrage that caused was remarkable, even though the proposed tattoo would be mainly covered, just for his and his partner's enjoyment.
Here is an article about a year old about Tattoo "penetration" in the USA.
http://fivethirtyeight.com/datalab/how-many-people-regret-their-tattoos/In fact, the highest numbers of people with at least one tattoo is 38% in the 18 to 29 years age group, so I think we should accept that many FBB's and fitness etc that we see will have a tattoo. Unless trends change, soon it will be more likely to see a tattoo than a clear skin, like it or like it not.
