I have a tattoo that I just got started on my butt yesterday. It’s going to take 16 hours at least to finish it and all I have done so far is the line work. I’ve had 3 other tattoos previously. One on my forearm a bit bigger than my fist was my first tattoo, one behind my ear and one on my wrist. I thought that getting a tattoo on my butt would be nothing because I felt almost no pain at all with the other three. I was dead wrong. You have three major nerves running down your backside: The femoral nerve, The sacral plexus, and the biggest one the sciatic nerve. The fact is that your butt is mostly fat, even if you’re a gym junky like I am. So instead of having a bunch of conditioned well trained muscles to protect your nerves from the shock, you instead have something barely covering them. Believe me when I say it’s painful but totally worth it. My tattoo artist wouldn’t even tell me it was going to be painful because he has done all of my tattoos and didn’t want me to back out on this one. He’s been tattooing for 30 years and he knew all along how bad it was going to be. The lying SB. Lol I thought I was being a wimp when I kept dropping the f bomb ( to my credit I did not cry at all) I’m getting a flying monkey done in full color on my butt, and It’s going to have the emerald city in the back ground with the yellow brick road, some poppies and a lot of detail. It’s going to be truly beautiful, but I now know what I’m getting into. Just do your research like I did and you’ll be fine.
