When I felt the same way as you 4 years ago, I did some online research in an effort to prepare myself to circ. my son. My research actually had an opposite effect - I decided circumsising wasn't needed and therfore we did not. He is 4 and we have no regrets. I was hoping to find the site I found back then but I cannot. There are so many out there. It was a good one though, it didn't take sides, it gave pros/cons on both issues, had a video, etc.. Anyway, you can google and probably find many videos to prep yourself. I did find the following site http://www.circumcisionvideos.com/ but I have not viewed anything on it. I don't know if they are for it/against it, or what. You should watch a few videos though if you are squeemish, so that you'll be prepared. My girlfriend did not want her son circumsised, her husband did, he took him for the procedure, the Dr. made a mistake (cut too much) he is 6 now and has had several reconstructive surgeries. Aside from infections, that is my only horror story. I know more people with boys who aren't circumsised and none of them have had issues. Things can happen either way. I just can't see cutting the most senstive part of the male's body off of him. They can always be circumsised later in life, but you can't put the skin back on - well, I don't know, maybe you can now a days? LOL!
Hope you find what you need, your little guy will be here soon! Congrats!
