Hi i'm 13 years old and I recently pulled back my foreskin (wasn't able to about two weeks ago) and it goes down a little bit when the left side can go lower but my right side is like its "glued" to my glans/it has been fused whats wrong with me? - TheBear
NOTHING is wrong.
The foreskin is fused to the glans at birth and separates after. It usually completely detaches by around 16 or so. Normal erections and masturbation help that happen.
Give it some time.
Start stretching your foreskin if you have not. Get an erection and pull down on the shaft skin so the glans spreads the opening - it'll help the foreskin detach too. Don't force it. Do it as often as you can.
By 16 you should be able to fully retract your foreskin too.
