Hello, I'm 17 years old and am uncircumcised. My foreskin is attached to the back of my glans by a fleshy string. I have always had trouble pulling back my foreskin all the way (its tight), but on the positive side, I haven't experienced any pain, swelling, reddishness, or allergy. Kindly tell me if this is something to worry about, or is it normal? Any help would be much appreciated.
As you are 17 , your body is still growing and so is your penis. Everything is normal in the pics.
Don’t forcefully pull back the foreskin ever. It will take another couple of years to become fully retractable.
Ensuring proper hygiene is in your hands. So keep it clean.
