I mean, people just like what they're used to.

If you never got circumcised, you'd likely be saying "I prefer uncut. Looks a bit weird with a piece missing."

I'm willing to bet if you surveyed, say, Israel or Saudi Arabia, on what looks better between chopped and natural, they'll say circumcised. And if you surveyed, say, Australia or Spain, they'll say uncircumcised looks better.
