Cannot say, it was too long ago.
Would never have been until I was at least a blue belt (ie beginning-intermediate ranking). Though warm up kicking back and forth certainly felt spooky-scary... (they were all much bigger, far more "worldly", and by far more agressive than I ever became...)
My first session, like I said am certain I got struck cleanly a whole bunch I am sure. Have to think on it maybe I'll remember, but for now guess I've been hit one time too many
My "chin blocks" are P-E-R-F-E-C-T-I-O-N incarnate
