How should I respond, and should I teach him how to do it?

Just tell him it's when a boy rubs his penis to pleasure himself. If he wants to know more, sit him down at the computer and point him to JackinWorld. If he asks to watch you masturbate and is really interested in seeing how it's done, that's probably okay. Either way, he's sure to get the picture, and he'll probably start masturbating, too.
