There are quite a few unusual and weird spots for placing a tattoo, such as the inside of the lip, on or under the tongue, as well as close to or on various private parts. These places can also be surprising, as they are not obvious unless specifically shown.
Placements on these body regions are among those that hurt the most while getting a tattoo. However, they can also last longer than those positioned on normal or more exposed areas of the body. Consulting with a good tattooist is advisable when it comes to placing tattoos on such unusual places.
