Depending of hetero or homo sexual, having the sex partner suck your dick while gently sliding his or her teeth up and down your cock.
After the prom you and your girlfriend are trying to do work. To get hard your girl not only sucks your dick but slides her teeth up and down your dick putting pressure on the dick making it hard as rock. If your girlfriend does this, she is giving you the Cheese Grater.
