I would work on getting him comfortable with the stick before you try to lunge him with it. I would start by letting him sniff if, then hold it up to his neck. If he wants to move around, that's fine, just follow him. I like to do this in a round pen so they can't really go very far. Don't jerk on the lead rope or anything, just let him move his feet. Don't take the stick off of his neck until he decides to stand still and relax - chewing, head down, etc. as soon has he relaxes,take the stick away from his neck and praise him. Do this over and over until you can flap in around his whole body, as well as hold it places like his back, legs, hindquarters, top of his head, everywhere !
After he is comfortable with the stick, I would start teaching him to yeild his hind and forequarters with it. Its pretty hard to teach them to lunge if they don't know how to yeild first.
