Tattoos- help!I know the deal on the pain but i wanted to know if for example i hate needles u know they use..?

the needles to take blood and do inoculation's with i really panic as i hate it its a really bad experience...is the pain anything like that as that would be a good indication of if i would be able to tolerate the pain as wimpy as that sounds lol. The location of the tattoo if i was to get one would be on my him under my stomach or at the side of the hip or somewhere obscure and it would be quite small like the size of a pound coin or 50p coin and would be in colour i would appreciate some insight i understand pain is subjective but if i know how it compares to blood taking with a needle like that i will know. thanks in advance
