I really want a tattoo however I'm very awkward and worried I might make the artist frustrated

Hello !!!
I turned 18 in January and I've always wanted tattoos and it was my plan to get one as soon as I turn 18. However upon further research I really psyched myself out because I'm so awkward. I would love to get a tattoo of Ash from FMF but I'm really scared of how my interactions with a tattoo artist would go. I have a reference photo of a tattoo of him that i really like and I know about where I want it on my body but I just don't know what to expect from an interaction with an artist. I also lack a lot of self confidence so when someone asks me a question I tend to just agree with what they say or just answer in a way that I would assume would please them or make them most happy.

I guess i'm sorta of asking what I should expect to be asked about ? and if anyone has any ideas on how to be like an easy client ? ? I'm completely fine with pain, but I just don't want to make the artist have a hard time if they are designing a tattoo or something so if anyone has any ideas on how to make there experience as easy as possible i'd really appreciate that !!!
