[DBZ] Why didn't Goku teach anyone the Instant Transmission?

Sure, I get the Android Saga. I get that Goku didn't have enough time to teach anyone. But why didn't he teach Gohan during the Hyperbolic Time Chamber? Or after the Buu saga? They had plenty of time to train that technique.

Goku is a fighting protege, even when he was a child nobody taught him the kamehameha wave he just did it and it worked. This was probably a similar situation the yardrats probably used it a lot and by just watching them and following them let him learn it so he probably doesn't know how to teach it. 

Edit: prodigy not protege.
