I'm circumcised. Its not horrible, but there's no good reason to do it. Oddly enough, my brother wasn't. He got a minor amount of ribbing from the other guys, but that was about it.
Think about it this way. What other part of your body would you cut off at birth without clear medical benefit? The male nipples aren't doing us any good. Why not knock them off?
Now, if you had to pick a part of the body to mess with, why that? If I had to pick one, the penis would be near the bottom of the list.
If you're doing it for religious reasons, I won't get into that argument. Again, its not the end of the world. However, mine was done because the doctor convinced my mom that it would be much more sanitary, safe, or whatever. Basically, it was a cultural practice that was backed by some non-science.
I've heard the "its disgusting" argument. I don't get that. I'm sure in cultures where women wear plates in their lips, women without them look nasty, but you get over it. As for the women who don't dig it on guys, you think that's absolute or cultural preference? I'm guessing the latter. Besides, if I dated a girl who broke up with me because I wasn't circumcised, I'm guessing she wasn't really a catch to begin with.
I'm also seeing a lot of misinformation:
"From what I heard, penile cancer only happens in those uncircumcised. You may want to do further research on that though."
Anytime you make a sweeping statement like that, and also say "You may want to do further research", you should probably hit google first...

Parts of this seem to point to higher incidence, but then you get this...
"The American Medical Association and the Royal Australasian College of Physicians say the use of infant circumcision in hope of preventing penile cancer in adulthood is not justified."
Some other stuff...
"A man is much more likely to regret not being cut." - I highly disagree. I think this opinion is the exception, big time. You've even got guys out there doing the following...

Socially, its going way down, so don't worry about that so much. Women prefer cut? Not sure where to start with those arguments. You want your son dating the type of women who would base the relationship on penis style? You really THAT worried about what women are going to think about your son's penis? As for disease prevention, there are plenty of other body parts you could remove to prevent disease. We generally don't do that until after there's a problem. The vast, vast majority of men in the world are not circumcised and things tend to work ok.
The only caveat is the HIV infection rate studies. These are recent studies. I'm sure they're going to look into things quite a bit more before they really understand the connection. Maybe you should wait till there's a little more data on that one.
From what I've heard, sex is more enjoyable when you're not circumcised. I wouldn't know, of course. I can't imagine making the choice to do it as an adult either.
Sorry for the rant. I just don't get it.
