Help! New relationship advice.

So I really like this guy I'm dating. We've been dating a bit over a month. We have fun, we're attracted to each other and we have the same values. However, we keep having some awkward moments and dates. There are times when I feel like I can be myself and other times where I don't even know who that is and I just go blank. Sometimes I just don't know what to say or talk about. Is this normal?
