That’s a good question.

Sadly many people are afraid to be direct.

But some maybe got burned out previously when tried to be direct. Some people react badly to rejection so if someone in this guy’s past reacted badly to him rejecting her, he might be afraid of being direct.

He possibly liked you but decided against sleeping with a coworker or he met someone else or wasn’t interested in sex after just two dates. Maybe he was just trying to be polite. Who knows.

Enjoying two dates or feeling comfortable doesn’t mean he is obligated to continue this especially if he’s asked to have sex after just two dates. Is it better if he was direct? Yes. But at this point it was only two dates so it’s better to move on.
