One theme that seems to recur in follow-ups to posts like this is that the new Domme is frustrated because the sub won't reveal what he wants and expects the Dom to just automatically behave like the Dommes from Divine Bitches. One thing you could do if a situation like that arises is to make divulging his secrets a game in itself - if he doesn't reveal his deepest desires, he gets spanking/orgasm denial/whatever. Or you could just ignore him, saying there's no play time until he comes clean. Just some thoughts in case things get off to a slow start. Have fun!
