Inverted Nipples

Lily

hi, i’m 13 years old and i have inverted nipples. from what i can recall as i never payed much attention to my breast they were inverted around puberty so became inverted when i hit puberty. i’m very insecure. also my breasts are very small. smaller than every girl i know my age. are my breasts small because of my inverted nipples? and can i change this without surgery? please help
