I have four tattoos, one on each ankle, one next two my belly button and one on my upper arm. It really all depends on where you get it, some spots hurt more then others. But what I have notice is your adrenaline is rushing when you go in, and it makes your pain tolerance higher then normal. Well it did for me
The tattooing gun has a motor on it, and it will go in and out really fast, it sounds like a buzzer. So there is really no way of tell how many times the needle will go in and out of you.
Make sure you go to a place that is up to health regulations, vary important.
I am sure you will do great, you will be so happy when you are done, you will want to get another one. Tattoos are additive
Good luck
