Circumcision can be delayed until a man can consent, but it's much more traumatic if done after infancy.
I'm one of those people that people just feel comfortable opening up to.
In college, one friend told me his dad was asking him if he resented his father's decision to circumcise him. His father had to get a medical circumcision due to recurring infection due to difficult sanitary conditions in mandatory military service in his country of origin (where circumcision is uncommon). The father's experience was terrible, decided his son should never go through that, and circumcised his son. Years later, he was second-guessing the decision. My friend wasn't sure how to respond to his father, since it was clearly weighing heavily on his father, but it was totally a non-issue for the circumcised son.
Another friend told me that he was circumcised at 12 due to recurring infections (in a first-world G10 country), and is a big advocate for infant male circumcision.
Anyway, there are statistically significant benefits from male circumcision, though they are often over stated. On the other hand, the downsides to circumcision are also minor for most men. For the average male in a G10 nation, circumcision seems to be low-risk low-reward procedure, though with large fat-tail distribution on both the risks and rewards.
