Looking like daddy - Do you remember what your dad's penis looks like? Or your mom's vagina? Did you ever sit around discussing the similarities and differences between you and your parents genitals? Should circumcised boys also get penis enlargement surgery and wear a pubic hair wig? Or perhaps Dad should shave and have penis reduction surgery? When you think about it, looking like Daddy is a rather asinine reason to subject your newborn to unnecessary surgery. "I was cut at birth so you should be too!" Illogical.
Its cleaner! - Cutting off any piece of skin means one less piece to clean, sure. But that doesn't justify it. Frankly, its insulting that people think that their sons will not be capable of bathing. Female genitals have far more folds and flaps of skin than male genitals do, but we manage.
It prevents the spread of disease - That point is disputed. For every study that comes out offering some tiny amount of protection from circumcision, there is another study debunking it. Even those studies that do suggest some benefits, the benefits are always described as miniscule. You know what IS a real way to protect against diseases? A CONDOM! I will teach my son safe sex instead of cutting him. By the way, no major medical organization in the world recommends circumcision. Just sayin'. Also, did you know that removing a girl's breast buds at birth will 100% reduce her risk of breast cancer? Breast cancer is a leading cause of death among women in the U.S., but removing a girl's breasts still seem horrific.
Religion- Your religion ends where another person's body begins. Muslims circumcise their daughters for religious reasons, but that is not allowed in the U.S. so it should not be allowed for boys either. Jews allow non-Jews to convert to Judaism so if your son wants to continue to live in the Jewish faith he can have it done as a teen/adult. There is no mandatory reason to have it done on the 8th day, especially since Jewish law states that any child born by a Jewish mother is a Jew.
Foreskin is useless, anyway - Oh no its not! It is there for a reason. One reason is to protect the glans (head of the penis). The foreskin remains fused to the glans for at least the first few years of life, and sometimes until puberty. It protects the glans from dirt and bacteria, while at the same time keeping it moist and sensitive (much like the clitoris or the inside of your lip. Soft, moist, sensitive flesh.) The sensitive glans and all of the highly sensitive nerve endings in the foreskin makes sex more pleasurable for intact men than for their circumcised counterparts, and prevents them from having to pound their women like jackhammers just to achieve orgasm. Another wonderful feature of the foreskin is as nature's gliding mechanism. You see, natural sex is not supposed to need lubrication at all, but the "helmet" top of a circumcised penis actually draws women's natural lubricant out of the vagina as the man pulls the penis out, causing dryness. Since circumcised sex is simply his skin rubbing against her skin it creates friction. When the foreskin is present it draws over the head of the penis when the penis is pulled out, thus preventing the glans from dragging moisture out with it. Rub the bottoms of your two index fingers back and forth together. Feel the friction? Now rub the bottom of one index finger over the *top* of the other. Feel how the looser fleshy skin on top of your finger glides under the other finger? That's an oversimplified version of how foreskin works. One more function of the foreskin is that it keeps the glans covered for the rest of the man's life when the penis is not in use which means that his glans is never rubbing inside of his underwear becoming desensitized and calloused.
Government should not be able to tell people how to raise their kids, so a ban on circumcision is wrong - The government mandates a lot about what you can and can't do with your children, and with good reason. You cannot rape your child, beat them, hit them hard enough to leave marks, leave them unschooled (as in not going to school or homeschooling), verbally abuse them, kick them out of your house, starve them, or amputate any body part (except for the foreskin) without a good reason to do so. The government won't allow you to cut the genitals of a girl, so they should be fair and not allow it for boy's either.
Peer pressure - The circumcision rate in the U.S. has dropped dramatically in recent years, and in most of the world circumcision is not prevelant at all. So if your child ever travels abroad they will be the odd one. And if they stay in the U.S., depending on where you live, they will be surrounded by 30%-75% intact peers. Besides, shouldn't we teach our children not to give into peer pressure? I think we should set a good example so when they are being peer pressured into drugs/sex/crime/whatever, they know that they don't have to give in and that they should stand up for what's right, even if it means they are different.
But I know someone who had problems! - An adult male in the U.S. was born during a time when almost all male babies were circumcised, and very few medical professionals knew anything about intact penises or cared. The advice given to parents of intact boys was to force the foreskin back to clean under it. That is the absolute worst thing you can do to an intact boy, and it opens the glans and urethra up to all sorts of problems and can cause permanent damage to the glans and foreskin and permanently increase the risk of infection. Besides that, females are about 7 times more likely to get an infection than males (cut or not) and most little girls have a UTI or two at one point or another. Some have very many, and continue having them on into adulthood. No one ever suggests cutting little girls to prevent it. UTIs happen. You drink some cranberry juice and take antibiotics if necessary and you get over it. I remember getting UTIs as a kid, they sucked. But I am glad no one ever cut me! I am also glad no one ever removed my appendix or tonsils "just in case" I get an infection.
But it looks "weird!" - That is a problem solely because of *your* perspective. To your newborn boy, its just the way it should be.
Long story short, there is no reason to have it done without consent. If a man wants it done he can have it done under general anesthesia, take pain meds afterwards to be comfortable, and not have to urinate/defecate all over a fresh wound by wearing a diaper.
He can always have it done at a later date, but he can never have it undone. He is the owner of the penis, he should be the one to make the decision, he's the one who has to live with it and use it everyday.
