i just brought it one time. He was lying on the bed, and i took his pants off with my teeth and i told him to close his eyes, and i put my vibrator under his scrotum. he loved it. [= we don't use it all the time, actually, only once in a great moon, but i does make it extra fun for both. So i guess, just introduce it in a sexy way, and i'm sure he'll looove it.
