I’m okay with pierced ears and smallish, tasteful earrings. Some Indian women look nice with a tiny stud on the side of the nose. It’s traditional in the culture. Guys shouldn’t have pierced anything. Any piercing that harms the health is out. Tongue rods, barbells, pierced lips, septums, eyebrows, cheeks, or privates including belly buttons screams, “I’m cheap and have no class,” to me.
Tattoos on women? No thanks.
If a guy has been in the military and has a tattoo that can be covered up, I understand. It would be better to not get it, but it wouldn’t disgust me if the tattoo itself was of something masculine and decent.
Other body mods like scarification, branding, foot binding, lip plates, etc. cannot be undone, so these should not be done. This isn’t to say one can’t become Catholic after the fact, but Catholics should avoid permanent body modifications.
I’ve seen women with Rosaries tattooed on their calves or arms. Sorry, to me that looks cheap. Why not wear a Rosary or carry one? Somehow, I don’t think anyone actually prays on a Rosary tattoo.
People covered in tattoos, piercings, and with other bizarre modifications looks demonic, imo.
If anyone wants to make lots of money in about ten years, just invent a method of effectively and relatively painlessly removing tattoos. Patent it and sell it to aging people with crepe skin!
Keep in mind, also, that tattoos and some Jєωelry is expensive. Better to give alms than to get a religious tattoo!
