Thigh tattoo pain?

I'm 16 getting a tattoo in october, The place does it with id and you dont need parental consent, i'm not in contact with my dad anymore andddd (no its not illegal cause there is no legal age to get a tattoo in bc) but i was thinking a flower piece with a hummingbird on my thigh. or a dragon on my back. which would hurt less? its my first tattoo obviously haha. i cant find a pic of the dragon tattoo but it would take up most of my back😬
