are my breasts normal??

i honestly don’t know if i can talk about this on here but, i (16) was with my girlfriend (16) a few weeks ago and she was just playing with my boobs and she told me she loves them because my nipples are small (about the size of a pencil eraser maybe even a bit smaller) and my areolas are completely smooth with no Montgomery glands? i realized her nipples are a lot bigger thicker and her areolas have those a raised bumps. are mine normal?? or do i have low estrogen or what? im just worried. any boob doctors here?

EDIT-

l like how they look i was just worried! tysm for replying, one more question- do you guys think they’re gonna change in the next few years for example, get bumps or get bigger nipples? since i’m still pretty young.
