If a guy you're on a date with says that he is...?

I think it is sweet of him. Alot of us guys would jump at the chance to get some action on the first date. He may just be a bit shy. I would just say see how the next date goes, and talk to him if he closes up. He may have been hurt recently and might not want to rush things. Just go with the flow for the while, he probably thinks you are a pretty nice girl if he wants to go out again right?
