Okay, this is a difficult situation. I‘m sorry that you had to go through this, and that guy definitly seems like an asshole.

I might not be the best judge in this situation because I‘m really uncomfortable with anything sexual, and it seems that this was obviously the case here. Depending on how close You are with the other people, I think you should probably tell them. This is sexual harassment (even though I‘m not clear if this is the correct term and I don’t know if you consider it that ) and as a friend I would probably want to know if that happened to my friend by another friend.

Again, I‘m sorry if you had to go through this. This must be a pretty bad situation
