Do people who outrageously lie about their pictures know that you have no obligation to have sex with them once you meet them?

I’m pretty sure there have been hundreds of posts about this topic.

I was chatting with this guy and we decided to meet, once I got there the guy managed to make me get in semi dark room, once he showed himself the guy is at least twice his actual weight, I’m not kidding.

He has sent pictures of other people’s body for sure. I said a big No, I can’t do it. It was the first time that I said No to a guy who lied about his pictures and this was too much for me to handle.
