Well, I do beleive all has been said about your inquiry:
1.It should be considered carefully
2.The old testament did say not to have them because the children of God were not to imitate the surrounding pagan cultures.
3. You may regret your decision
4. Other christians may take offense to it
5. Other non- Christians may take offense to it
6. Doors may close in ministry because of it
It is your decision, think carefully, and pray a lot about it. Remember, God won't stop you from jumping off a cliff if you really want to, but you have to deal with the consequences.
I have a friend who has a few tatoos (about 5) that are all "Christian", and I don't hold anything against him for it, but I have heard people talk badly about him getting them- christian and non-christian alike. And all I know is, from a short distance, they don't say anything about God- but are just tatoos. You have to be standing near him to distinguish. Think about it.
God will love you no matter what. Forgive me for not finding it, but it does say in the bible that to he who considers something to be a sin, then it will be for him.
