I too, was wondering how it turned out for Caroline since the baby has arrived. Hopefully, she convinced her dh...
I know I'm finding this thread late, but I thought I'd put in my two cents:
I never thought much about it, just sort of assumed it was what you do to a boy. But then when I started realizing I wanted a homebirth, and not only that, but an UNassisted homebirth, I inevitably was lead to info regarding circumcision. The first time I brought it up to dh, about a month after we found out we were having a boy, it was a very tense discussion with him adamant about circing (Dh is circed). I didn't push it - in fact, I told him that I wasn't going to fight tooth and nail, and that ultimately I would defer to his wishes, BUT I said that I really felt uneducated about it and thought we should really do our homework first and have a darn GOOD reason for doing it before we just blindly did it. And I said I didn't think "to look like Daddy" was truly a good enough reason.
I then read for about two months on the topic and was horrified at what I learned. But here was the kicker: I found a website that showed all of the variations in the look of adult males circumsized penises, and it explained how ALL of these variations (most of which I had seen in my single days) were actually due to circumcision, and NOT how a penis is supposed to look. This just blew my mind! All of this time thinking back on the penises I had known, and thinking they were God's variations, when NO, actually they were all due to circ injuries!

So, then one day while laying in bed after sex, I casually said to my dh, "Did you know that your penis looks like this because it was circumsized?" And I pointed out two characteristics he had. Well, he was quite shocked! I then read aloud to him a few things I had come across, and then gave him one article to read against circing written by an MD. It mentioned that penises are usually longer and more sensitive when intact. Well, that was it. A few days ago, he told me we didn't have to circ our boy and that he was really ok with it! I am so happy! I think the part of him feeling he may have missed out by being circed was what got him.
HTH!
