16m, just found out my foreskin is supposed to retract fully past the head (without pain). what do i do?

i know this is a condition called phimosis, i just don't know what to do. my parents haven't really talked about puberty at all, and kind of expected me to figure it out.

it's kinda uncomfortable to pull it back more, although i'm not sure that it's physical pain. it is kinda more just general un-comfortableness that occurs when trying it.
