A Tiny issue

So I recently started stepping out with a really nice guy. Total package. He's cute, sexy, handsome, smart, dedicated, and a perfect gentleman.
We decided to have sex last night for the first time. I have never wanted a guy more.
And then his pants came off and his dick was smaller than his balls. I didn't say anything to him and he did grow a bit in the process, but I was kinda shocked how small he was.
He's not eaten me out or anything yet but I imagine he's really good at that. I'm highly sexual but I know he's shy and very self conscious about his body. What can I do? I've tried reassurance but nothing has worked. Even having sex the second time.
