Take these kind of charts with a grain of salt.

As someone who has several tattoos it's different for each person. Personally the worst pain I felt was on a specific part of my wrist and I have tattoos in my armpits.

A friend of mine says their worst tattoo was the one on their ass and another friend says the worst was her thigh.

It's generally accurate but everyone's different.

Scarring is also a factor. Scar tissue reacts differently than normal skin. Sometimes it can be less sensitive and other times they can be more sensitive.

Someone should get this chart as a full body tattoo. Please report back; I'll be waiting.

Reminds me of this:

I would also like to point out the humour in me finding that on 9gag with some other watermark.

I have a palm tattoo, and I would definitely give that a red. I dread going to get it renewed.

Interesting that 1) donating blood uses a red spot, and 2) the colors don't change continuously (there are blue-orange jumps skipping yellow, and yellow-red jumps skipping blue).

Tattoos on the butthole aren’t great, got it, duly noted

The problem with these charts is that it all varies so much from person to person. I would put the entirety of the waist to the back of the knees as red. Nothing sucked to me as much as the back of the thighs and butt.

Of course I got my first tattoo on the inside of my wrist...
