The operation of circumcision is very imprecise and some doctors leave more skin than other doctors, so there is a lot of variation.

Circumcision is a horrible operation that greatly damages the penis and its functions. If less tissue is removed less damage is done. Be thankful that you still have some of your foreskin.

To the extent that your foreskin covers the head it protects it. Furthermore having loose skin adds skin mobility which aids in masturbation.

You might consider starting foreskin restoration to stretch the remaining foreskin to completely recover the head. That would restore your normal intact look that the circumcision destroyed.

Just search for "foreskin restoration" on line and you will get lots of information.
