I often try to look at what may very well be hidden between the lines (and often find out later I was smack on-target, but this may be more of a leap... so forgive me if you have knowledge to the contrary...)

I have come back three times and have read your post three times... and I wonder if he is as experienced as you might think.

He may not talk because he doesn't wish to reveal that he might not know as much as you think he does, perhaps not even as much as you do. There are some (very rare) naturals out there who just do it right... but you may well be his first actual sub.

My first submissive was totally overwhelmed by my skills and "knowledge" and dominance. She never, to this day, realized she was my first.

The woman who I first openly topped, experienced things she said she'd never done before, was transported fully into sub-space (I was a bit surprised by that too btw) and had a great time.

The other possibility is he doesn't want to overwhelm you.
Another is he may just get off on listening.
And yet another may well be he loves newbs... and doesn't want you to get too comfortable or worse complacent.

For those latter two, you have to talk to find out his preferences (and just put it that way.) And unless he wants it, don't train yourself. Let him have the pleasure of molding you into exactly what he wants from you.
