Honestly, no penises look good - neither do vulvas. They're very weird looking things, as to be quite honest are any body parts when looked at in isolation. Circumcised or not, they aint pretty!
I couldn't justify it except for medical reasons; as I see it, it's equal to removing the clitoral hood. If this was done routinely or for no medical reason there would be an outcry, as there should be for removal of the foreskin.
