Nipple Piercings

I am an 18 year old girl and I have always thought about getting my nipples pierced. I always thought they looked cool and that they could make me feel better about myself. I also have serious self confidence issues in general but I hate the size of my boobs. I am a 5’1 girl that is only 130 pounds and my boobs are literally 32DD. I HATE them. They just are so in proportional to the rest of my body. Not only do I not like the size of them, but I hate my nipples. I swear they are inverted which I know is “normal” or whatever. I’ve even had my friends look at them and they are like yeah?? i guess so. My boyfriend swears they are just flatter or whatever. Also on top of that they never do their function. They never get hard or like being touched. They aren’t sensitive and don’t react to anything. THEY SUCK. Would getting nipple piercings help me?
