To circumcise or not...

That is the question! I have a 2 year old and I have not circumcised him. I did not want to and I still do not want to. I have had several people throughout the last two years telling me it's weird that my son isn't circumcised, that it simply looks weird, that it's not clean, and it makes me question whether or not I made the right decision. Can I have a little input please?
