I would love for you to do that to me, but I would like you to cut my testicles with your knife only. I want to have a penis. As for the balls, I don't need them anymore, because they cause me trouble because of the hormone they secrete.
My testicles are at your service, make them resistant to torture, but I believe after the lesson is over, my testicles will be ground and castrated, and I will be a castrated donkey in the service of girls forever.
