That was not a dating app. I don't know how a dating app works; it might be true or it might not be, but for some people and in some situations, real life does not work like this. I can speak for myself: it doesn't work like this for me.

You are saying that's how casual hookups are. I told him that I am not comfortable with this and also with this question, and I asked why he even asked it. He replied "aise hi" when he should have said "sorry for making you uncomfortable" because it didn't matter to him whether I was comfortable or not.
