I've had a very similar experience with Koike Sensei, I remember I couldn't shake off his hits for days all I could think of was how intimidating it was to be standing in front of him. For the life of me I couldn't escape him either, the hits just kept coming in, until I realized the only way I could attempt to avoid them was to keep up my attacks at the same rate. Of course I wasn't hitting him, but just the act of going for men at the same time caused both of our shinai to miss. In my mind, I beleive that is what he was trying to teach me, without verbally expressing it.
