I want to get a tattoo

Talk with the artist who's going to tattoo you as much as you need. I'm guessing he knows better than most of us, even if we're tattooed. They're usually really nice and cool people that will answer all your questions and even help you with the design if you're not 100% sure what you have is what you want. Their suggestions are good, and they have a better idea of how it's going to look once it's done, so ask them as much as you want. The most important thing for me was feeling comfortable. Even the pain goes away when you're feeling comfortable.
Oh, don't go with someone that you might find annoying/stressing or that might make you feel anxious. I went with my mom and she was asking me "are you nervous? are you nervous? are you nervous?" for like 30 minutes, when I was under the needle I was so anxious that the pain was annoying. The appointment after that, I went alone and it wasn't so painful, I was relaxed and actually enjoying myself.
