I am from Toronto. I was circumcised as a child. Now as an adult it has been figured out the foreskin was not fully removed. I went to a doctor and he stated that I can undergo a recircumcision to remove all of the remaining foreskin. Currently when erect the glans is exposed, however when flaccid the glans is partially covered.
I clearly understand that circumcision is a sunnah and not a must. I personally prefer to undergo circumcision again and remove all of the remaining foreskin. Is this something permitted in Islam or should I avoid it.
