It used to be far more important to circumcise your child but with advances in medicine and safety it's not as vital. It's a very personal choice. An uncircumcised penis has a better feel and sensation during sex. Not to mention saving your son from minor surgery. Circumcision minimizes risk of hygiene caused diseases and sexually transmitted diseases. But in our country this is not much of an issue.
I chose to circumcise my son. I did it mostly for the disease protection. While. It is not as much of an issue in our country, it still is in other countries. For me it was an issue of safety and better to get it done while he would have no memory. I would also mention, circimcision as a baby is a very quick procedure but as a teen or adult will require a two day hospital stay. It's a much more major procedure the older a man gets.
