I could never get a tat anywhere near my privites.....that's a big boundary.
Supposedly the roughest place to get one is the ribs. That was my first one and the guy kinda tried to talk me out of it, because I wanted something that was gonna take hours and required shading.....and he was worried I wouldn't be able to tolerate it.
It DID turn out to be far more painful than I was expecting. It legit was like hot razors being drug across my bones.....and i started laughing at how bad it was. He kept asking if I was okay, needed a break....I said nope get it done.
I scared the guy a bit lol.
