OK I am not circumcised and other males laugh when they see my penis and it's not
Circumcised like theirs, and also made fun because it looks ugly.

So what are the pro's and con's being circumcised.

There is normally a religious or medical reason for this procedure.
Personally, if everything is functioning correctly, leave well enough alone.

The penis isn't exactly a pretty appendage anyway, so these comments are clearly coming from some serious insecure people.
