that's the thing, everyone is different and this could be true in his case.
Agreed. Neurology can be crazy unpredictable. The pain of circumcision (and/or the recovery, if anesthetic was used before cutting) can have long-term consequences for a baby's brain and the nerves running through the genitals. It's already been proven that circumcision (anesthetized or not) negatively affects breast-feeding.
I have a pet theory that anal sex appeals more to circumcised men, because so many of them lack the fine-touch nerve receptors that make intact sex so delicious. They look for "harder" experiences, such as a tighter orifice, to try to get what they're missing.
