I have an inverse/bottom navel piercing. Growing up in The Philippines, I saw all manner of piercings but it wasn't until I came to the US when I learned that such a thing as navel piercings existed. I never thought anything of the navel before other than being the umbilical scar every person has but the placement for piercing on that area intrigued me so much that I just had to have one myself. I pierced mine on my own which is the only reason mine is inverse because it was easier to do than the top. I know it wasn't the smartest decision but I think mine turned out well. I've had it for four years and have no regrets.
