When to take out piercings??

When is it inappropriate to have nipple rings and a tongue ring? My tongue ring is not noticeable. Most people don't even know I have it for months before I laugh really big or do something that shows my whole tongue. No one sees my nipple piercings except my boyfriend but sometimes I don't feel like wearing a bra and it's very noticeable. I don't want people thinking I'm trying to be young and grasping. At what age should I take them out?
