Oh God, now I feel like an idiot for my comment that you should get the tattoo because it wouldn't hurt. I am sorry.
Don't sweat it, you didn't know. And anyway, it wouldn't hurt. I have such a high pain tolerance now, I've gotten needles in places many wouldn't want to think of so it's okay. I've gotten tons of needles on my hip and they didn't hurt so a hip tattoo would be easy-peasy for me.
