Yeah the logistics involved would be a nightmare.
All back to hers? Could be miles away.
Also going against porn tropes again, most men who didn't know each other would be not keen on going off with a load of strangers and 1 girl to (wherever) and then having sex in front of all of them... A lot of men are pretty shy about this stuff despite what we're told, and would not be interested.
House parties when at school maybe? That would be a possibility. Or teams of sportsmen, who do seem to be into this, it's a team bonding thing I suppose. Consent often optional, reading the news.
Agree not sure what this adds to the conversation.
