I have my right nostril, the left side of my bottom lip, the right side of my upper lip, my tongue, and my ears are stretched to 0 gauge.
I also have 2 micro dermal implants on the right side of my neck (I call it a "vampire bite".)
My grandma raised me and she was a very strong Roman Catholic, but she felt that piercings were fine. She wasn't a fan of tattoos because they were permanent, but piercings can be removed.
