At first thought, I thought it was weird that he would know so much. Then I realized it's probably because 12 year old boys irl, and even adult men, don't quite understand how female anatomy and genitalia works. So good on him for learning about this stuff, especially if he is looking for a hyena girlfriend in the future. Don't want to be caught unprepared if she dies in childbirth
Also, I'm surprised the furries don't take advantage of this more often. Or maybe they do. I'm not into futa, much less futa furries. Please don't @ me examples.
