Girls: Can you help me, please?

I have been going out with this girl who is 22 and in college. She is SUPER classy, polite, and just an absolute down to earth sweetheart. She goes to church and loves God and her family. She has told me that when she was 19, she got her nipples pierced, but don't have them done anymore. I was so shocked. She only has her ears single pierced now and that's the only piercings she has. She said her and a couple of her friends got a wild idea about getting them done, so they just went for it. She said she really enjoyed having them done, and it made her feel more confident in her body, but she didn't want to keep hiding them from her family. What do you think about this? Is she too wild?
