I want my lip pierced, my boyfriend's parents though..?

They hate piercings. His last 2 girlfriends cheated on him, the one had a monroe and nose, and tongue. And the other, had a monroe, and belly on. His parents sorta have that impression left on them, that girls with piercings are skanks.. I have 3 lobe on each side, a forward helix on the left, and a cartilage on the right, and a belly piercing. Honestly, I love his parents, they treat me like I'm their child, and we're really close. I'd never cheat on Devon, but I don't know if they know that. I want to please them, like I would my own parents. His parents don't like my piercings, I don't think. I want a conch piercing on the left, and a tragus on the right. I've wanted my nose and lip since I was a kid. I don't know what to do :( Their opinion means a lot to me.
