Here is our story:
my DH and I were like you two...one for, one against. Also, DH is Jewish and it was simply expected that if we had a boy, he would be circ'd.
HOWEVER...never underestimate the power of a determined mommy!
For one, I worked at Presby before having DD, in the postpartum unit. And every morning baby boys were lined up and circumcised-all (and I mean ALL) screaming their little heads off, no matter who the ob was performing the circ, what "analgesic" they used, or what method was used. It was horrible, and not something I ever wanted my baby to go through.
I told DH that if he was dead set on having it done, I wanted him to simply educate himself on the how's and why's of the procedure. I wanted him to watch a video of a circumcision (not one that influenced people either way-but a factual video showing the two methods so he would know what our baby would be going through). If, after all that, he still wanted it done, I asked that he be with our son when it was done. I didn't want him to be alone, surrounded by strangers that were hurting him, and scared. AND...after all that, I didn't want to hear him say "Wow, I wish we hadn't done that" (which is exactly what a friend's dh said after their son's circ). I just wanted him to educate himself.
We got as far as dh looking at a diagram of how it's done...he refused to watch the video and said "that's fine, we don't have to have it done".
Then our baby was born, and it was a boy! My IL's came over and their first question was "when is his bris?" Um....never? you should have seen their faces, it was so incredibly tense in our house. DH actually caved and after his parents left he started pressuring me to circ the baby. I was pretty upset. We had made the decision BEFORE the baby was born and then, when his father was unhappy with his decision, HE switched teams and left me out to dry?
We went back and forth for about two weeks...I just kept saying "but we decided BEFORE the baby was born...you can't let emotions change a decision that you made based on facts" and he kept saying "I don't know WHY I want it done, I just do".
Finally, he asked our Ped. I had no idea, but her son isn't circ'd. Neither are most of the boys in her practice (if you want her name, she's wonderful, email me!). She gave a HUGE talk on how unnecessary routine circumcisions are, and how more and more boys are left intact these days. The whole "locker room" argument is going to be obsolete.
So after that he let it rest. My baby boy is four months old now, and every time I change his diaper I am so GLAD we didn't circ him. He is perfect just the way he is.
Oh, and at a playgroup not long after he was born I was changing his diaper. None of the moms have seen an intact penis and gathered around. The moms of boys said they were sad they had circ'd their boys and regret it. the moms of girls said they were unsure if they would circ their future boys or not...but after seeing Ben and how "normal" it looks, (and we are not a hippy family by any stretch), they are more open to the idea of leaving them intact.
