I kinda think mine looks like it's attached to the foreskin, it hurts if I pull it back while erect and I'm worried it's abnormal. Anyone care to shed some light on it? Pic here:

Yep, sure looks tight.

Mind you, it does not seem to extend that far on the foreskin. I presume you actually have to pull it back quite firmly to hurt it and I always point out that such force is not a part of "normal" sexual activities.

Suggest you get to work on the stretching - note - the way we describe it here, not just pulling your foreskin back.

You can increase your comfort level by lengthening your frenulum. Look for the directions on the locked thread on this page.
