Hello
(I turned 13 a month ago)When i get errect the foreskin won't be pulled down(i can only see the head a bit) and if i try to pull it I feel pain.

When im not errect the pennis is fully using the forskeen,it's more than enough so it leaves around 1cm (it seems like the pennis has 1extraCM of foreskin). At that time i'm able to pull it back.

I haven't tried to pull it back when im soft and then get errect because i'm pretty much scared... :-(

(PS. I haven't tried masturbading, i dont know if i can)

Any advice would be really usefull...
Thanks a bunch
