I've only heard of two guys voluntarily getting circumcised for non-medical reasons. One guy did it because his newborn was getting it and the other just thought it would be better for him. Neither had regrets.
I'd do it except I was told getting an erection during the healing process would be extremely painful.
If the circumstance arose, I'd also have my child circumcised. It's better/easier for cleaning and many people think it looks better. I'm not concerned about giving boys a choice considering most boys will never consider or actively choose to get circumcised given the sound of the process and plus, guys who are circumcised at birth won't miss what they can't remember having.
