I agree that it is good for them and for many of the reasons listed. Chuck will never admit that he enjoys it when I fuck his boy-hole, and I think I prefer it that way.
This is good for you. Don’t try to squirm away. Come back here! It’s going to stay in. It is going to go in and out. You may as well learn to accommodate it. You may never like it. But, you are going to learn to accept it. Regularly. Women have had to accommodate their men since time immemorial. With their sex. Those males acted like bulls in copulating with sweet womanhood. Now, you’ll understand what it feels like when a bull rudely and ruthlessly penetrates you for its pleasure and not yours. Turnabout is fair play.
