We have class Mon, Tues, and Thurs. Every Thursday, we do some sparring. Last night was my second sparring session. My sensai pointed out, which I also noticed the previous week and last night, when someone takes a swing at me, whether it's a kick or a punch, I tend to drop my hands slightly and kind of lean forward a bit. My sensai said, sooner or later I'm gonna get my head knocked off if i don't fix that . It almost seems to me maybe I'm afraid of getting hit . Any advise of what I can do to avoid this is greatly appreciated. Thanks everyone.
