I know some of these practices are done for religious purposes, but I am not a Muslin nor Jewish. I am a Christian-Catholic and I will do what is best for my child as a Christian-Catholic.
There are TEN BAD REASONS TO CIRCUMCISED YOUR SON:
(taken from http://www.associatedcontent.com)
It Looks Bigger
One thing that some people believe about circumcision is that a circumcised penis will look bigger. Risking a 2-10% chance of medical complications so your son can have the illusion that he has a larger penis is just not justifiable. When your son is older and if he feels that he would like to create this illusion, which isn't necessarily true, he can make that decision. There is no need, if there is ever a need, to have a larger looking penis when you are a child, or for that matter an infant.
It is More Aesthetically Pleasing
This is a personal opinion. Truth is, it is likely that when people are actually going to be examining your son's penis with the intent to view it as potentially being pleasing to the eye it will be erect. Therefore if you are worried about loose skin, which isn't the case anyway, hanging from the tip of the penis when it is not erect don't worry the only people who will see that is yourself, when your son is an infant and child, and your son. If it truly bothers your son he can make the decision when he is older to circumcise himself.
It is Less Sensitive and Therefore the Sex Life of Your Son's Future Partner will be More Enjoyable
There is no reason to make decisions when your son is an infant that will affect the sex life of his partner. Every individual is going to be different in bed and some men intact and circumcised may climax earlier then others. With this kind of thinking you are ultimately saying that you are circumcising your son so he will not enjoy sex to the fullest potential.
It Will Be Easier to Clean
A circumcised penis is exposed to everything that it comes in contact with. If you have ever changed a diaper, one that is full of poop, you will know that poop does not stay in the rear section of the diaper, it gets over everything. While a circumcised penis is healing it is constantly being exposed to urine and feces. When an intact infant boy poops in his diaper you still have to make sure that you wipe off all of the poop on his penis but you can do it a lot easier. Your son's penis will not be sore because he did not have minor surgery on it. Once your son is older he can retract his foreskin, something that happens naturally and should be done the first time by the owner of the penis, all he needs to do is pull back his foreskin and rinse that area. Something that is going to take less then a minute.
It Will Look Like the Other Boys in the Locker Room
As a woman I will be honest in saying that in the locker room I don't remember that there were ever any comparisons of reproductive organs and from all of the men that I have asked about the matter, both circumcised and intact, said that they never saw or experienced a conversation like that either.
It Will Look Like His Father's
Not really. Infant penises are hairless and that will be the biggest difference that your son will notice if he sees his father's penis, and of course the size.
My Brothers Were Circumcised
Nothing against your parents, they were doing what they were educated to do, however in this generation a lot more medical evidence has proven that times have changed and circumcising isn't medically necessary.
Your Son Will Develop a Complex for Being Different
Once again as a woman I can vouch for myself not having these feelings but I can say the all of the intact men that I know and have asked about this matter say that they do not at all fill insecure about their intact penis.
I Believe That it is Medically Healthy
It is hard to know exactly what is medically correct, between friends and family you may get told a little of why you should circumcise and why you shouldn't. That is why is is always a good idea to do research when making a medical decision. I guarantee that you will find that a circumcised penis is not medically healthier than an intact penis.
The Doctor Said To
As much as I would love to say that we can trust all doctors and what ever a doctor says is going to be the right thing, I can't. My doctor told me that he didn't like his patients to go past 38 weeks in pregnancy, but it didn't mean that inducing at 38 weeks is medically the right thing to do. Remember, research is the only way that you can know for sure what is the right thing to do about anything.
When your son grows up he most likely will not have a reason to get circumcised, but if he wants to make that decision it is best that he is the one making it as an adult and not his parents while he is an infant and without his consent!
