Is it bad she never compliments me on my looks?

There is this shy girl and we have liked each other for a while. We just started dating together and our first date went really well. Generally speaking, everything is cool and fine. There is one tiny problem though. Well, it's not really a problem... but I wonder why does she never compliment me on my looks? Does that mean I'm not attractive enough for her? I'm not looking for an ego boost but I've been told by other people that I'm a good-looking person (sorry, I don't mean to sound narcissistic) so I'm just curious if she thinks I'm attractive. I've complimented her a few times... be it her looks or her personality... etc.
