That's a pretty big shaft to 20 1/2 or so years of your life, your body, and your emotional state, to be frank. I can already see the weariness in her eyes! Bravo!

I guess in nature there is nothing better to do, but observe just how many female animals have developed ways to struggle or resist copulation! Why I wonder.
