how do i get more comfortable and uninsecure with my boobs?

so i’m very insecure with my body. I hate one of my boobs because it’s deformed than the other and little .. And also i have a third nipple looking thing underneath that boob... Also i’m insecure with my nose , cuz it’s big .. I have a boyfriend and i do want to be naked in front of him and have sex naked but i can’t cuz i’m so insecure and tense.. because of my boob. how do i look myself without getting surgery ? 😩😩😩😩😩it’s just my nose and my boob that’s making me insecure with myself
