Research where to put it. Make sure you put your tattoo over muscle. Otherwise it will hurt more. Stupidly, I put mine on bone. Check which design you want. Be careful because you will always have this. Shower directly beforehand. Go to get your tattoo alone. This way if you change something, there will be no confusing comments that you might regret.
After you get your tattoo, put a salve on it once or twice a day. It's called Tatwax (soothing balm). If your tat itches, just slap it. Don't shower for a day and let the wound scab over.
