Here's another view or two:

Maybe you have met an actual honest-to-the-gods Alpha that doesn't really give a rat's ass about this Thing That We Do and the forms and conventions that we follow. Just maybe he has no interest whatsoever in learning on your terms but is comfortable enough in his own skin to do things his way and expand and learn as he sees fit.

Conversely, maybe he's uncomfortable with this part of him and is afraid to admit that he really is a dominant with sadistic tendencies. It can be scary to come to grips with this stuff and admitting who and what you are.

Note: I assume this man is not married and is free to be seen anywhere he chooses with you in tow?
