Are Nipple piercings “bad”???

I told my bf I was getting my nipples pierced on Saturday and he wasn’t happy about it. He doesn’t think I should do it even tho it’s my body plus who would see them?? He says that it would be noticeable thru my clothes since I don’t like bras and that he doesn’t want anybody touching my boobs aka the piercer. It sounds dramatic to me! What do you guys think? It’s my body and idk how i feel about him being upset about it because it doesn’t change anything. Am I wrong?
