I've been dating this guy for a week and its really awkward?

I feel really awkward with this new guy I'm dating. I think we're moving too fast, like the awkward kisses in the hallway, him awkwardly my thigh under the table, him ALWAYS being there, holding hands with me when I don't like holding hands. I feel really insecure for some reason when I'm around him. Whenever we make eye contact thats closer than a meter apart I feel awkward. Its just all very uncomfortable. Will it get better? Will it end? What should I do?
