We circumsized our children because it is a cultural, traditional thing to do, because it can prevent infections later down the line, it's easier to clean, to prevent ridicule and such in the locker room as they age, and frankly b/c it is just more attractive.
However, there is more awareness and controversy surrounding it now, a lot of men are wishing they had the choice to do that themselves. Really, there is little benefit to circumcision, and it actually reduces the amount of pleasure a man can feel. It makes me a little sad now that I mutilated my son's body parts without any real medical reason. I watched a video on a traditional non-anesthetic circumcision and it was incredibly intense and painful, I hurt so bad for that screaming, traumatized baby... it is a much bigger procedure than just a little snip. Of course, in US hospitals, the procedure is not that intense, but accidents still happen and penises do get mangled. Many more parents are choosing not to circumcise, so I don't think it will be as taboo in the future as it is now.
At the same time, many people who do not circumcise, sometimes will have to do it anyways when their child is older if it gets infected.
So, there are really pros and cons on both sides, truly a personal decision.
