Do I touch my Girlfriend too much?

I have been dating this girl for exactly 2 weeks. I get to see her once or twice a week. But every time we are together I finger her and give her a hickey. Is it too much? She moans when I do it and seems to like it but I don't want her to think that I only want her so I could touch her. I love her. Should I lay back or something for a bit?
