hiii! im 15 years old but i started going through puberty 1.5 years ago and im still growing. Im a BB cup and have perky and tight breasts but i have noticed that my nipples are too low as all my friends and people from the internet have their nipples higher up. I don't have a big gap for under boob and i have a big space between my breasts. is there anything i can do to get more under boob so my breasts are pointing upwards??? my beats don't sag at all tho. i have also noticed im not sensitive at all when getting felt up by a guy and my nipples are usually soft . will they ever change ?
