My wife and I are expecting, and we are not finding out the sex. However, if we have a boy, she is adamant that we not circumcise him, and I am adamant that we do. I have researched article after article about the hard medical facts of circumcision and how it lowers the transmission rates of STD's such as HIV. It also helps with penile carcinoma, UTI's, and ulcerative STD's.
My intelligent wife believes that we should offer our son a choice of whether he wants it or not, and is afraid our son will feel the pain if he has it.

I am circumcised, and want my son to 'look' like daddy, as well as not have to explain to him at a younger age as to why he is so much different than daddy.
Furthermore, if the procedure is done later, our son will be in pain for six weeks, and I just don't want him to have to endure that torture.
As circumcision requires both parents consent, this matter will not resolve itself. I feel that my wife should consent as I have more experience in this matter than she does. I would also feel inferior when our son asks, " Daddy, why did you cave in to mom's demands?" later in life.
We are at an impass. We are both passionate about our beliefs (she would consent to having our son circumcised if I were Jewish).  What can I do? Should I let this battle go?

While it’s OK to have differences of opinions, I would hope that you don’t have to have actual battles over these issues. Perhaps because you’re both acting so stubborn, neither one of you is willing to listen to reason. And at this point, you don’t even know if it’s going to be a boy or a girl!
While you raise good points regarding the health concerns, those risks are greatly reduced if it is a boy and you teach him to clean his penis thoroughly. I know not every young male does a good job at that, but if this is important to you, then you’d just have to make it your duty to make sure he does.
Your wife’s point that the decision should be his does not sound very intelligent. It is much worse to have this procedure when you are older, so the decision must be yours when he is quite young.  If that’s her only concern, then perhaps your argument that you want his penis to look like his dad’s has more weight. But in the end, this is not such an important issue and rather than fight over it, you should have some reasonable discussions, if the baby turns out to be a boy, and see what happens. But better to lose this particular debate than fight with your wife.
