I'm sorry that happened to you. The guy should have read the social cues better and not been so aggressive.

But in his defense, as others have said, Grindr is all about hooking up for sex. There are guys that want to date and their profiles clearly state that they will not fuck on the first date and that they need to get to know someone well before that's going to happen. Otherwise, most guys expect a meeting to lead to sex unless the person clearly says, "This isn't going to work out. Sorry."
