Why won’t he touch me?

I’ve been dating this guy for about 6 weeks and about 3 days ago we officially became bf/gf. The issue is that he doesn’t seem to want to touch or kiss me. We haven’t kissed on our last 3 dates. I slept over last night and was trying to cuddle and he told me to “move over”. I’ve brought it up and he acknowledges it but it’s only getting worse. He’s never had a gf and I’m trying to be patient but I’m getting tired of it. Any advice? Should I try to stick it out or just get out while it’s fresh?
