I'm 15 and yesterday I attempted to pull back my foreskin I have left it over night. But now I have two air bubbles in the foreskin it self. It also hurts when I try to pull it back.
Attempted? Did you get it back and/or how far? I don't see how you could get air bubbles in it I think what you see must be something else like maybe a little bit of swelling. Or if you DID get it back behind the glans it probably doubled over itself when it went forward which is nothing to worry about it will straighten out by itself in time or after the next time you pull it back. Pull it back behind the glans, get it wet and slide it forward. You should be able to grasp the tip and pull it forward to smooth it out.
