I've been to a few gangbangs, it's always been interesting, the people we're cool. I do have to admit an orgy sounds fun whether watching the activities or being watched
I've never been to an orgy, and it's an exciting fantasy. The reality might be a little harder to deal with. The dynamic just seems easier to deal with when it's one on one or a menage a trois. Any more than that and it just seems like too many cooks in the kitchen.
But you never know, it might be fun watching a room full of people fuck while you're getting it on yourself. All the visual stimuli, you know. But it might be sensory overload, too.
