Who and how coerced you, though? If you were too close to the stage, did someone hold you there? Was it impossible to take a couple of steps back? If the crowd was so thick and tightly packed that there was no opportunity to move back, that is a circumstance, not someone's intentional act. I wonder what you perceive as coercion.

Nobody here thinks that you are a slut. We were telling you that the performer might have perceived you as signalling to him that you were a groupie. I also want to mention that perhaps unintentionally, but you might now be slut shaming other women, true groupies. I am sure this is not something you actually want to say, but this comes across as implied. While we might not associate with groupies, they are people with a full set of rights and claims to respect. There is nothing wrong with wanting male attention, nor with getting it. Groupies are not lesser women, lesser people, or lesser citizens.
