When your out to dinner rub his **** through his pants under the table...that will get him fired up. Also send him texts throughout the day that you can't wait for him to get home...you can use your imagination on what to put in those messages.
Tell him he's got a big nose and point at his glasses and laugh. That should do it.
Tell him how attractive you find his brother or best friend
tie him up withhard on and then go outand buy some nice shoes
