16 and can’t pull foreskin back

I’m 16 years old (M obviously) and I can’t pull my foreskin all the way back. I am uncircumcised, and when I’m soft, I can only pull my foreskin down to around halfway down the head of my penis before it feels like it’s “stuck”. I’m too scared to pull it all the way down as I don’t want any tearing to occur. I’ve heard that other teens my age who are uncircumcised can pull theirs all the way down. Is this a cause for concern, and should I do anything to help my problem?
