Does he think I'm pretty?

I'm insecure about my looks. I've been dating this guy for a few months and he'll jokingly say things like, "C'mon, you're gorgeous, let's go!" when he's ready to leave for somewhere. He doesn't tell me what he thinks about my looks in a serious way, though. Can I assume that if he's dating me then he finds me at least reasonably attractive?
