He gets physical when he can't "get me down" as my sensei likes to say. Apparently I'm really sensitive to intent, and if there isn't enough of it, it doesn't work. He usually ends up royally frustrated whenever he works with me. Thank you for the advice.
Some people tend to disconnect after their initial attack. Such people are difficult to throw, but since they aren't actually attacking, who cares?
Without getting my hands on both of you, I wouldn't necessarily agree that *his* intent is missing. It could be yours. Or it could be both. Neither of you is really senior enough to assume that what you're doing is "right." More likely, the flaws in your ukemi directly align with the flaws in his technique.
