foreskin not retracting properly

hi there well my foreskin dosnt retract properly i think i have a frenulum breve but im only 12 so seeing a doctor is kinda not gonna happen and i dont really wanna talk 2 my parents about it but yeah if anyone can help or give me some info i can only retract some of it enough to see most of the head but not the whole walnut as i was saying i think its a frenulum breve becuase when i try to pull it back the frenulum just wont let me and when it is pulled back theres a big build up of skin at where my penis starts plus thye skin is quite tight and i cant just pull it back easily it dosent hurt to bull it back but i just cant get the skin to budge
it may be because my penis hasnt started growing and there isnt enough room to pull back all the skin but to be honest i just dont know so will someone please help me
