Guys, please, some of the stories you are describing constitutes straight out sexual assault. You have a responsibility to speak up and do something about it and help those who are being victimized.
If you want to fantasize about these sorts of situations, go ahead. People have all sorts of fantasies and these hurt no one. But in a real-life situation where any kind of non-consensual touching is happening, you have a moral responsibility to stop it. Not just stand by and watch. You need to intervene.
Please learn to distinguish between your own "porn" fantasies and real life consensual behavior. Respect other people's boundaries.
