I would also question if the victim had any freedom to say no.
Picture it. You are very drunk, naked, having sex in a strange hotel room with a man you met an hour or so ago. A strong and physically fit man. It's his territory, not yours; it's his room.
Suddenly the door is opened and another strong man walks in. It becomes clear that the first man told him to come. He hasn't been invited by you, he hasn't knocked, you don't know who he is, but clearly there's some understanding between him and the guy you just met. The man who has walked in watches the sex then walks forward, unzipping, asking the other man if he can have a go.
There are other friends of theirs outside the window trying to film it, without your invitation or agreement.
Remember, you are naked, drunk, in a strange hotel room, with two strong men who have had absolutely no regard to your privacy, autonomy or opinion thus far and more outside the window.
Do you think anything you say will change what happens next?
