After reading about the Orthodox Jewish practice of sucking the blood, I sure view the practice as barbaric.
I think medicine and hygiene have moved on from the times when circumcision had any demonstrable benefits.
As to the original question, the practice of complete removal of foreskin was apparently not practiced in Jesus' time. That was introduced around the 2nd Century. So Jesus' circumcision was not what is done today.
And God's edict to Abraham about circumcision was some while after Adam.
