Women who have participated in a gangbang: how did the situation come about, and what was the experience like for you?

I’m curious about real experiences rather than porn portrayals. For those of you who have been in a gangbang (whether planned or more spontaneous):
• How did the situation develop / how was it arranged?
• What did it feel like physically and emotionally while it was happening?
• What were your overall thoughts during and afterward?
• Would you do it again, and why or why not?
No judgment—just genuinely interested in hearing different perspectives. Thanks to anyone willing to share
