I wouldn't get tatoos or piercings, because I think they spoil the natural beauty of the human body. My son's girl friend, who used to have piercings took out the pins and so on and let them heal over. She's a beautiful girl anyway (on the inside too), but I think she finally grew up. But then, that's just my opinion.
No matter what we look like, God did a pretty good job most of us (and I make an exception only for hidious deformities...which can mostly now a days be corrected), and we shouldn't try to improve on the design.
