You're not already wishing you were done, are you? We're just getting warmed up. There is so much else to do to you today.
Give me 100 more medium strokes. After that, form a circle with the thumb and forefinger of your dominant hand around the base of your nutsack, so that is pulled away from your zero-stick. With your other hand, I want you to use the tips of your fingers to rapidly slap your balls for one minute. Doesn't have to be really hard - trust me - just rapid and firm.
