Do you peel an orange before you put it in a juicer?

Excuse me, but I have a rather curious question that's been bugging me for quite some time. It's about oranges and juicers, specifically. When you're preparing an orange for juicing, do you typically peel it first? I've seen some people do it, and some don't, so I'm genuinely curious about what the norm might be. I'm hoping you can shed some light on this for me. I mean, does peeling the orange make a difference in the taste or quality of the juice, or is it more of a personal preference thing? I'd love to hear your thoughts on this.
