Just sit down & talk to him about it hybrid.
If you want something from him, it's up to you to convey that in a way that works.
There's probably a hundred different things you can do, but ultimately it gets down to you guys working out what you both want with each other.
Have fun & let us know how it goes.
Edit- one other thing springs to mind, that there's a perception that any guy should automatically know how to Dom someone. That's not the case at all, if a sub knows more it's up to them to 'take the lead' as it were. We all have to start somewhere, & I for one learnt a lot from a very experienced sub.
