First tattoo advice

My birthday is coming up and I was thinking about getting my first tattoo! I really like the idea of a butterfly tattoo (they've been very symbolic for me). I'm indecisive about placement, I really like the inner upper arm and the ribcage but do those spots hurt more/less? I would kinda like to place it somewhere less visible but I still want it to look good. Please share your opinions on the placement/what would hurt less and maybe some advice! I would really appreciate it :)
