"From First Kicks to First Steps" by Dr. Alan Greene has a long and quite good section on circumcision. He helps parents to see things from their son's perspective (instead of just saying "whatever you want to do is fine"), talks about sexual functions, debunks the locker room, and points out that not all circumcised men are happy about begin circumcised, and once its gone you can't put it back. He does not describe the procedure step by step, which is maybe what you're looking for, but gives a gut level picture of how the baby probably experiences it: "If you were a baby, would you rather spend time in your parents' arms, gazing into their faces, listing to their coos, or be taken away by a stranger, strapped into a plastic restraining board, stuck in the genitals with needles containing local anesthestic - or worse, not stuck - and have a nerve rich part of your genitals severed, leaving you inflamed, tender, and uncomfortable for hours or days?"
